Code Snippet Python doing exact match on string

kbalamuk — Thu, 24 Dec 2009 20:30:44 GMT

I want to replace 'nf' with 1.0, so that the resulting string should be:
'(1.0+nfpermult+1.0)'

I tried various approaches using find(), re.sub but I am not able to make it work.

eg. re.sub('nf', '1.0', str) replaces all occurrences of nf. also re.sub('\bnf\b', '1.0', str) does
not work either as 'nf' can be anywhere in the string.

any ideas?

8 Directional Movement

BlackPhoenix — Thu, 24 Dec 2009 20:11:04 GMT

Hi everyone,

having trouble coming up with the right code for 8 directional movement [ up, upright, right, downright, down, downleft, left, upleft]

My keypress handling is:

if event.type == KEYDOWN:

            if event.key == K_LEFT:

                player.moveLeft = True

                player.moveRight = False

            if event.key == K_RIGHT:

                player.moveRight = True

                player.moveLeft = False

            if event.key == K_UP:

                player.moveUp = True

                player.moveDown = False

            if event.key == K_DOWN:

                player.moveDown = True

                player.moveUp = False

        if event.type == KEYUP:

            if event.key == K_LEFT:

                player.moveLeft = False

            if event.key == K_RIGHT:

                player.moveRight = False

            if event.key == K_UP:

                player.moveUp = False

            if event.key == K_DOWN:

                player.moveDown = False

And my directional checking is:

if self.moveRight == True and self.moveUp == True:

            print "MOVE UPRIGHT"

        if self.moveRight == True and self.moveDown == True:

            print "MOVE DOWNRIGHT"

        if self.moveRight == True and self.moveUp == False and self.moveDown == False:

            print "MOVE RIGHT"

        if self.moveLeft == True and self.moveUp == True:

            print "MOVE UPLEFT"

        if self.moveLeft == True and self.moveDown == True:

            print "MOVE DOWNLEFT"

        if self.moveLeft == True and self.moveUp == False and self.moveDown == False:

            print "MOVE LEFT"

        if self.moveUp == True:

            print "MOVE UP"

        if self.moveDown == True:

            print "MOVE DOWN"

It worked fine until I added the last two statements for moving up and down: It fires off MOVE UP and MOVE UPRIGHT at the same time, for example.

This also seems more complicated than it needs to be. Can you help make this work, and if possible, help me find a more efficient, easier solution?

Thanks

Hello everybody,

I am having trouble to create the following script: I would like a screenshot been taken each time a click is detected. Also (if possible) to be able to modify the x and y of the size of the screenshot.
There is my code (doesn't work yet):

import pyHook

import ImageGrab



def onclick(event):

        img = ImageGrab.grab()

        img.save("screenImage1.jpg")

        return true



hm = pyHook.HookManager()

References or Ebooks

Democles — Thu, 24 Dec 2009 05:47:19 GMT

I'm not sure this is the correct forum for this, but it's at least relative. I was wondering if anyone knew of some decent references and ebooks for a beginning Django user.Yes, I know djangoproject has tutorials, but there decently hard to understand. If someone could either help or steer me in the right direction would be great! I would prefer free, I cannot afford a book or ebook at this moment. Christmas and other issues.

Thanks

Access method of class instance that assigned class

xvalentinex — Thu, 24 Dec 2009 01:04:14 GMT

Okay python gurus, this one has me stumped. Is it possible to introspect and obtain the instance of a class that assigned a class?

I have a simple sample that demonstrates what I'm looking for, but doesn't make any sense why you would do it.

class One(object):

    def print_parent_hw(self):

        ?????????

        ?????????.print_hw()



class Two(object):

    def __init__(self):

        self.cls = One()

    def print_hw(self):

        print "Hello World from One"

    def have_one_print_two(self):

        self.cls.printparent_hw()



a = Two()

a.have_one_print_two()

I could do it by rewriting some code, but this situation could be cleaner and quicker (even though the sample doesn't make much logical sense). I realize I could do it like this, but it doesn't seem right, and you end up with a circular attribute (i.e. a.cls.parent.cls.parent.cls.parent.cls.......)

class One(object):

    def __init__(self, parent):

        self.parent = parent

    def print_parent_hw(self):

        self.parent.print_hw()



class Two(object):

    def __init__(self):

        self.cls = One(self)

    def print_hw(self):

        print "Hello World from One"

    def have_one_print_two(self):

        self.cls.print_parent_hw()



a = Two()

a.have_one_print_two()

decoding arbitrary byte data

ribot — Wed, 23 Dec 2009 04:41:00 GMT

Hello, I'm trying to deal a bit with IRC and Python 3. The decoding from bytes to Unicode create quite a dilemma.

1. Somehow it works to convert the å character from utf-8 to bytes, but the received bytes seem to often be encoded in latin-1, or at least they can be decoded correctly as that. Does this mean that on IRC servers the data being transmitted can be encoded characters of any arbitrary set (utf-8, latin-1, etc)?

2. If that is the case, is there then some way to figure out what the encoding is? Because the utf-8 codec cannot decode the character \xe5, which latin-1 decodes to å. utf-8 decodes \xc3\xa5 to å. Seemingly, there is no way then to know what encoding is being done on IRC?

3. My approach to this problem is that I can take the OS default charset. For example, using tkinter, there must be some charset being used in the text widget. How can I find this out? At least then, for an IRC client, the language used by the system will be decoded properly when chatting.

Colour picker problem

pyguy420 — Tue, 22 Dec 2009 14:25:29 GMT

Im trying to write a code for a colour picker, so a user can pick 4 different colours and then it would return them so i can use them in a different par tof the program, but its not working properly and i can work out why. any ideas?

def colourpicker():

    print "pick four different colours from; red, green, blue, yellow, orange, pink, brown"

    colourList = ["red", "green", "blue", "yellow", "orange", "pink", "brown"]

    coloursPicked = []

    while True:

        colour1 = raw_input("pick first colour: ")

        if colour1 in colourList:

            break

        colour1 = raw_input("not in list, pick agin: ")

    coloursPicked.append(colour1)

    return coloursPicked

    while True:

        colour2 = raw_input("pick second colour: ")

        if colour2 in coloursPicked:

            break

        colour2 = raw_input("colour already picked, pick again: ")

        if colour2 in colourList:

            break

        colour2 = raw_input("not in list, pick agin: ")

    coloursPicked.append(colour2)

    return coloursPicked

    while True:

        colour3 = raw_input("pick third colour: ")

        if colour3 in coloursPicked:

            break

        colour3 = raw_input("colour already picked, pick again: ")

        if colour3 in colourList:

            break

        colour3 = raw_input("not in list, pick agin: ")

    coloursPicked.append(colour3)

    return coloursPicked

    while True:

        colour4 = raw_input("pick fouth colour: ")

        if colour4 in coloursPicked:

            break

        colour4 = raw_input("colour already picked, pick again: ")

        if colour4 in colourList:

            break

        colour4 = raw_input("not in list, pick agin: ")

    coloursPicked.append(colour4)

    return coloursPicked

i think some of the loops might not be working how i want them too, but i cant seem to work it out.

Get Keys from a dictionary of a dictionary

playonlcd — Tue, 22 Dec 2009 09:16:09 GMT

I have read some documentation about python, but no examples on how could you can extract Keys from a double dictionary.
To understand better here is an example:

Let's say we have the following dictionary:
{'AAA': {'KEY1':'text1', 'KEY2':'text2', 'KEY3:' 'text3', 'KEY4': 'text4'},
'BBB': {'BBB1':{'KEY1':'text1', 'KEY2':'text2', 'KEY3:' 'text3', 'KEY4': 'text4'},
'BBB2':{'KEY1':'text1', 'KEY2':'text2', 'KEY3:' 'text3', 'KEY4': 'text4'},
'BBB3':{'KEY1':'text1', 'KEY2':'text2', 'KEY3:' 'text3', 'KEY4': 'text4'}}}

How can i extract KEY1, KEY2 and KEY 4 from AAA and KEY3 KEY4 from BBB1, BBB2, BBB3 in BBB?

Rewrite the code to make sure there are no duplicate numbers amongst the six numbers displayed.

Now let the user enter six unique numbers from 1 to 50 and then count how many tries it takes the computer to match 3, 4, 5 or 6 of the user's numbers, using the above random number example. You might recognize this as a way to figure out the chances to win a lotto game.

Not sure if this is the place to ask but I want to write a similar program that list all possible combinations and have it displayed in the Notepad program. Where do I start? And how do I write a search program (with parameters that I set) that filters the results?

Thanks!

Creating a tuple from file

hondros — Tue, 22 Dec 2009 05:29:25 GMT

Okay, so I have a tuple for a game, and this is it:

['Hondros', {'Equiped': [['none', [], 0], ['Rags', [0, 1, 0, 0], 1, 1], ['Mocassins', [0, 0, 1, 0], 1, 1], ['Gauntlets', [0, 0, 0, 1], 6, 5]], 'Equipment': [0, 1, 1, 1], 'Stats': {'AC': 14, 'Strength': 15, 'Constitution': 14, 'Level': 1, 'HP': 12, 'Experience': 0, 'Dexterity': 12, 'Intelligence': 12, 'Base AC': 8, 'Wisdom': 11, 'HP max': 12}, 'Inventory': [], 'Gold': 0}]

Anything inside it can change, including number of tuples inside the dictionaries. Anyways, this is how my program stores the character's information. There might be more added on. Now, this is what I want to do. I want to open a file, convert the tuple to a long integer, through use of the ord(). I've already done this, and saved it as character.sav, where character is the character's name. Now, when I open it, and convert it back, I now have a string of the above tuple. How do I go about reconverting it? Doing a tuple of it just makes it weird...

EDIT: Er... I seem to have my definitions of tuple and list confused... these are lists, not tuples. Oh well... same difference really

Small directory management project.

lrh9 — Mon, 21 Dec 2009 19:39:39 GMT

I'm thinking about writing a small command line directory management program in Python. The most basic functionality I want is to be able to compare the the files in a directory and sub-directory, and if there are any duplicates then delete the lower most duplicate.

I all ready have a basic idea of how to accomplish that. Merely hash both files and compare the hash values. If the hash values are equivalent, then they are the same. However, I'm not sure on the specifics of how to accomplish it. I know the data has to be read from each file and then hashed to do the comparison. However, what is the best method for reading the data? I'll be dealing with large files, possibly upwards of 4GB, so the program needs to be able to handle this.

What are some other good tools to include? I'm thinking about writing some file renaming tools as well.

Multiplication program help

teenspirits — Mon, 21 Dec 2009 12:05:17 GMT

I made this code:

import random

wish = "j"

max_multiplications = 10

while wish == "j":

    multi = 0

    right_answer = 0

    while max_multiplications != multi:



        randomint1 = random.randint(1, 10)

        randomint2 = random.randint(1, 10)



        print randomint1, "*", randomint2, "="

        ik = float(raw_input ("Insert your answer "))                  

        multi += 1                   

        answer = randomint1 * randomint2

        

        if ik == answer:

            right_answer += 1

            print "Correct!Good Job!"                                  

        else:

            print "Wrong answer!"

                             

   

    else:

        wish = raw_input("You want to try again? [j/e]")

But maybe someone can help me now. How can I put into the beginning ,that the user can choose how many multiplications he wants to solve(not 10) AND if the user inserts a wrong answer he can try again.

Thanks! :)

Okay, I am in the middle of creating a rather large console RPG. It'll include ability to equip armor, weapons, interacting with NPC's, battles, saving/loading characters, etc. I don't want to save all of my classes and functions in the same file, for easier readability. I have a few questions:
1) Can I import .py files that are in the same folder to a separate .py file?
2) How does this change py2exe? Do I just setup the script for the main one, or all?

Derived Classes

Garrett85 — Sun, 20 Dec 2009 18:53:34 GMT

In the program below, I have two questions. First, the first object, card1 passes the strings A & c to it's master class. What I want to know is, what do these two strings have to do with the A & c in RANKS & SUITS? If the class had been based the number of the element in RANKS & SUITS I wouldn't be confused right now but I don't see RANKS or SUITS being used.

Secondly, why is there an __init__ method inside the Positionable_Card class with rank and suit, but is then instructed to use rank and suit from it's base class? Thanks for any and all replies.

simple function help

ffs82defxp — Sun, 20 Dec 2009 05:52:35 GMT

lets say i want to make a function that accepts a single argument that is supposed to be a number.

lets say the function displays the range between 0 and the argument.

Normally I'd do something like this:

def range_display(integer):

     set = []

     for num in range(0, integer):

          range_list = set.append(num)

          return range_list

But I don't know if thats how functions accept arguments. Just a guess.

How exactly do you make functions accept arguments? I don't quite get it...

Updating a wx.listbox from a different class

ShadyTyrant — Sun, 20 Dec 2009 05:27:04 GMT

Hi there daniweb, im looking for some help. I have two classes MainWindow(wx.Frame), and AddTask(wx.Dialog). MainWindow contains a listbox called task_list. When AddTask is created I want the user to fill out the required info and and then click a button activating an on_click event. In that event I want to update the list in MainWindow. How ever when I try to do so I get and error: 'MainWindow' object has no attribute task_list.

Here is what I have tried so far (not full code):

class MainWindow(wx.Frame):

   

    def __init__(self, *args, **kwds):

        kwds["style"] = wx.DEFAULT_FRAME_STYLE

        wx.Frame.__init__(self, *args, **kwds)

        self.create_tasklist()

        self.create_toolbar()

        self.set_properties()

        self.do_layout()

        self.bind_events()



    def create_tasklist(self):

        choice_list = ["TaskOne", "TaskTwo", "TaskThree"]

        self.task_list = wx.ListBox(self, -1, choices = choice_list)

......



    def on_add(self, event):

        '''Adds new task to task_list.'''

        add_task = AddTask(None, -1, "Add Task")

        add_task.ShowModal()

        add_task.Destroy()



......



class AddTask(wx.Dialog):

    '''Custom dialog to add tasks to task list.'''



    def __init__(self, *args, **kwds):

        kwds["style"] = wx.DEFAULT_DIALOG_STYLE

        wx.Dialog.__init__(self, *args, **kwds)



        self.create_widgets()

        self.set_properties()

        self.do_layout()

        self.bind_events()

......



    def on_add_button_click(self, event):

        # Adds task_name to task_list

        MainWindow.task_list.Insert(self.task_name_text.GetValue())

I have also tried other variations though I think this one shows what I am trying to do the best.

error using wx.AuiManager

Indran — Fri, 18 Dec 2009 23:32:39 GMT

Hi Gentlemen,

I have an error, which was non existant when i used wxpython 2.8.7.1. When i upgraded to 2.8.10.1, basically the GUI got messed up.I am using Python 2.52 environment.

The error seems to be from the fact that the parent, in this case
MyFrame(wx.aui.AuiMDIParentFrame), is the default frame, which means i did not have to have a wx.window passed as the argument, while, auimanager seems to look for a panel to attach too? Please take a look at the self running code below. Any comment is appreciated.

Thank you very much

RPG Armor System

cnuzzo — Fri, 18 Dec 2009 20:00:44 GMT

I have been teaching myself python for several months and have started working on an rpg project. Right now I am trying to code an armor class for a basic character. I am not sure if my approach is even a correct way to go about implementing this class. The armor list items consist of a name, armor location, it's stopping power, weight penalty, and its cost.I managed to get the code to keep track of things then I realized if I append a new armor it will of course add it to the end of the list and I really want 3 designated slots to assign to. I would really appreciate some help with the code or even a thought process to help me rework this code. Any help would be appreciated. Thanks in advance.

File searching problems

harpalss — Fri, 18 Dec 2009 17:59:07 GMT

hi there got a couple of probs, say in my text file i have:

abase
abased
abasement
abasements
abases

--------

This coding below is meant to find a word in a file and print all the lines to the end of the file. But it doesnt, it only prints out my search term and not the rest of the file.

    search_term = r'\b%s\b' % search_term

    

    for line in open(f, 'r'):

        if re.match(search_term, line):

            if search_term in line:

                print line,

Say i searched for abasement, i would like the output to be:

abasement
abasements
abases

----------

My final problem is, i would like to search a file a print the lines my search term is in and a number of lines befer and after the searchterm. If i searched the text example above with 'abasement' and i defined the number of lines to print either side as 1 my output would be:

abased
abasement
abasements

    numb = ' the number of lines to print either side of the search line '

    search_term = 'what i search'

    f=open("file")

    d={}

    for n,line in enumerate(f):

        d[n%numb]=line.rstrip()

        if search_term in line:

            for i in range(n+1,n+1+numb):

                print d[i%numb]

            for i in range(1,numb):

                print f.next().rstrip()

But i get a i get a Typeerror: unsupported operand type(s) for %: 'int' and 'str' which occurs at: d[n%numb] = line.rstrip()

Help please?

How can I write a definition for a function that is passed a list of numbers and returns the sum of the numbers in that list using a while loop?

I'm trying this, but it's not working

Need help with pygame to exe

sinisterduke — Thu, 17 Dec 2009 20:26:00 GMT

So i made a small game using pygame, and I want to be able to give it out to some friends who don't have python, so I want to make it into an EXE. i've been trying for several hours using several different methods, but nothings seems to be working. I would REALLY appreciate any help.

So after all this time I think py2exe appears to be the best tool to use. I have it installed, I just can't get it to work correctly on my game. After looking for many different setup.py file thingys, this is the one i've been using most recently:

When I try this however, I get the error:
NotImplementedError: font module not available
(ImportError: MemoryLoadLibrary failed loading pygame\font.pyd)

In my actual code, I'm loading font using:
font = pygame.font.SysFont("freesansbold", 48)

as I heard this is the better way to do it.

I've tried many different setup.py files, but each gives me a different error, whether it be missing DLL's, or font, or something else. If I could get any help with this, i would appreciate it.

Opening Files Question

JuvenileMango — Thu, 17 Dec 2009 18:10:40 GMT

What is the difference between

file = open("name.txt")

and

file = open("name.txt", 'r')

?

I can still use the methods: read(n), readline(n), and readlines(n) without adding the "r" in the open method.

py2exe and tkSnack

yvos91 — Thu, 17 Dec 2009 16:51:58 GMT

Hello everybody,

I made a wonderfull software, using Windows / python26 / tkinter / tkSnack.
As long as I'm on my computer, it works fine.
I try to distribute it, using py2exe. And I've not found the way to include tkSnack in the distribution.
I tried also with pyInstaller, with the same result.

I guess there is something to write in the setup file, like packages="tkSnack".

Does someone have an idea ?

Hello good day guys. I just want to ask for help in my java python. I am just new in this language.
MY first java language is java. However, for me to make it easier to code in python, i need to code it in java first and then convert after. But i am confused working with arrays in python, help me guys. Thank you.

import java.util.*;



public class sample {

        static Scanner scan = new Scanner(System.in);

        

        public static void main (String args[]){

                sample();

        

        }

        public static void sample(){

                

                System.out.println("Enter numbers : ");

                String input[] = new String[5];

                for ( int i = 0 ; i < input.length; i++){

                        

                        input[i] = scan.nextLine();

                        

                }

                for ( int i = 0 ; i < input.length; i++){        

                        System.out.println(input[i]);

                }

        }

}

I need your view on this project

evstevemd — Thu, 17 Dec 2009 14:41:28 GMT

Hi guys,
I have always wanted to write MP3 encoder in Python. I heard of Py-lame but I have never had hands on it and it is, to me a myth.

Ok after trying thinking in ctypes, I thought the best way would be using lame.exe and subprocess. But as I'm thinking of it, I hate black screen. I want to use my own GUI using wxPython. So, is it possible to use subprocess without having black screen? Also getting encoding progress and nicely display it on progress bar?

What do you suggest buddies? Thanks alot ;)

Hello, I need help with editing this program:

    if len(sys.argv) == 2:

        main(int(sys.argv[1]))

    else:

You can probably tell what this program does so I shall not elaborate. However, how can I edit the program so that it works for (for example) 4 goats and 1 car? Of course

DOORS = ['car', 'goat', 'goat']

needs to be changed but I'm not sure what else. Also, what does

return randrange(3)

do?

Thanks :)

Image Problem with Tkinter

Ash_Pokemaster — Thu, 17 Dec 2009 14:04:46 GMT

Hello pals.

We're having a project to make a Backup and Restore program in Python. As we think that making a GUI is of course very important, we started using Tkinter after initially trying wxPython which was kind of difficult given the time we had.

Either way, we made a Class where the main window is. Inside this Class, there is another Class defined, which contains the code of the another Window, where one can chose the options of the backup proccess. So, here's the thing. While we have made two text entries and two buttons, when trying to load an image, or any label for all it matters, it just won't appear, and we get the following error in Python Shell.

Exception in Tkinter callback

Traceback (most recent call last):

  File "C:\Python25\lib\lib-tk\Tkinter.py", line 1414, in __call__

    return self.func(*args)

  File "C:\Users\Ash_Pokemaster\Desktop\project_e31\kuygku.py", line 110, in backup_window

    back = Backup(buwind)

  File "C:\Users\Ash_Pokemaster\Desktop\project_e31\kuygku.py", line 94, in __init__

    self.labelcho = Button(framebu, image= photocho)

  File "C:\Python25\lib\lib-tk\Tkinter.py", line 2012, in __init__

    Widget.__init__(self, master, 'button', cnf, kw)

  File "C:\Python25\lib\lib-tk\Tkinter.py", line 1942, in __init__

    (widgetName, self._w) + extra + self._options(cnf))

TclError: image "pyimage8" doesn't exist

Here is the code along with the images.
http://rapidshare.com/files/32165819...t_e31.zip.html

We would appeciate it if you could try create an image inside the Backup Class, and figure out what the problem is.

So far, this is what we type between the two text entry eidgets, and of course doesn't work:

                photocho = PhotoImage(file=choose.gif")

                self.labelcho = Button(framebu, image= photocho)

                self.labelcho.image = photocho

                self.labelcho.pack()

                self.labelcho.grid(row=2, column=0)

Image "choose.gif" is not inside the zip, but I guess any image would work...

Thanks for your time.

Hello all,
One simple question.. We can set Tab bar for the tab widget in pyqt...
I want to place a push button on tab1.. In what way i can do that??? Should i have to add this in the first tab in tab bar or in the tab widget directly.. If i'm not clear, in QTabWidget we will add the components in this sequence
CreateWidget-->Add it to the tab(addTab)--->Add it to the QTabWidget..

In the same manner how should i use QTabbar..
CreateWidget--->Add to TabBar--->Add it to the Tab(in Tab Widget)
or
CreateTabBar---->SetTabBar and CreateWidget---->Add to the TabWidget ...
Explain me in detail...

Python Socket Programming Client and Server

erunways — Thu, 17 Dec 2009 07:10:00 GMT

Sockets are one of the most popular means of network communication and they follow client-server architecture. I have created two programs, one to run on a client computer and

the other on the server computer. In my program I am showing how using a sockets client program can communicate to a server. The client program is run at the client-side while

the server program runs in the Internet. I am using a socket module which is provided by Python. When the client runs the echo-client.py program it is prompted to enter the

address to the server which could either be a domain name which I used for the testing or an IP address. Keep in mind that the server side program echo-server.py has to be running

in order for the connection to be established. Once the user enters the address to the server it’s prompted to enter a message for the server. Once he enters the message and presses

enter the message is send to the server. The server side program gets the message and displays it and also returns it back to the client. The final step for the server is to close itself

once that one cycle is complete. The client on the other side displays a message that the message has been received by the user and even shows it just to so the user is sure of it and

finally closes itself.

Problem in zipping folder using PYTHON

ziashahid — Thu, 17 Dec 2009 06:03:49 GMT

Hi,

I am zipping a folder and an error occurred in below code which says :
==> AttributeError: 'builtin_function_or_method' object has no attribute 'tell'

zipfile.py:

def write(self, filename, arcname=None, compress_type=None):

zinfo.header_offset = self.fp.tell()    # Start of header bytes

...

...

FYI:I have tried using "from zipfile import *" instead of "import zipfile", but of no avail.

What is causing this problem?

Zia

My code to zip a folder:

check letters

leegeorg07 — Wed, 16 Dec 2009 18:02:07 GMT

Hi again,

I am trying a competition entry (its old, purely to test myself) and I have come against a problem, this is the description for the competition:

In a word game each letter has a score based on its position in the alphabet, A scoring 1 through to Z scoring 26. The object of the game is to split the letters of a word into two groups so that the total score of the letters in each group is the same. For example, LIONHEAD can be split into LIHAD and ONE, both scoring 34.

and I currently have this code:

import cword

running=1

while running==1:

    poss=[]

    print"""

do you want to:

1)enter a word?

2)quit?

"""

    menu=int(raw_input(''))

    if menu==1:

        word=raw_input("what is the word to check?")

        if cword.check_word(word):#checks is word is a word

            for pword in cword.dicta:

                if len(pword)
                    for letter in word:

                            if letter in pword:

                                if cword.val_word(pword)==cword.val_word(word)/2:#gets value of possible and current word, /2 bc new word value will always be half of the original.

                                    if pword in poss:

                                        continue

                                    else:

                                        poss.append(pword)

            print poss

    elif menu==2:

        running=0

    else:

        print "that was not a proper command"

        print "please enter a new one."

    

raw_input()

When running this with 'tiger' as the word, I get these possibles:

['ais', 'aria', 'awe', 'bags', 'beau', 'bind', 'bred', 'cate', 'ceil', 'cepe', 'crag', 'cue', 'dike', 'dip', 'ecu', 'ell', 'ex', 'fard', 'feme', 'fend', 'fer', 'fin', 'gabs', 'gang', 'gape', 'glee', 'glia', 'haik', 'hat', 'held', 'hep', 'it', 'jar', 'kale', 'lake', 'leak', 'lice', 'mig', 'page', 'peag', 'peh', 'pica', 'raia', 'raj', 'ref', 'rib', 'sade', 'see', 'tace', 'ted', 'ti', 'wae']

but how can I go through these words so that only the correct amount of each letter is used?

Many thanks in advance.

Howto change def. everytime its called?

Hi, I want to change a variable in a definition everytime it is called.
for example:
when I click on button, it will print 1
when I click on button again, it will print 2
Is this possible?
I have written this code but it doesnt work :)

if n:

    k=k+1

Need to simplify a loop thing

hondros — Wed, 16 Dec 2009 15:27:26 GMT

Okay, so what I want to do, is to take the following code, and make it so that way it keeps continuning for all of the word.

keycode = raw_input()

matrix = [0, 0, 0, 0]

for x in range(0, len(keycode)):

    y = ord(keycode[x])

    if x > 3 and x <= 7:

        x = x -4

    if x > 7 and x <= 11:

        x = x -8

    if x > 11 and x <= 15:

        x = x -12

    if x > 15 and x <= 19:

        x = x -16

    matrix[x] = matrix[x] + y

The part I want to continue is the if statements... I'm thinking maybe using the len(keycode) somehow, but I'm a bit confused on where to go from here. Any help would be appreciated.

Threading & Thread: speed performance between modules

baskar007 — Wed, 16 Dec 2009 13:51:11 GMT

I have two questions on python threading:
1: is there is any speed performance or difference between Thread module and Threading module?

2: Is there is any other major difference between Thread module and threading module?

I used thread module for my download manager project.
i think this thread module does not doing parallel works. is this correct ?

tkinter: not mapped instantly after grid()

ribot — Wed, 16 Dec 2009 13:09:55 GMT

Hello!

My application is crashing randomly, and I thought it might have to do with it manipulating widgets that are not yet mapped, despite them being already gridded. Have you experienced this problem?

I supply some code that shows that the print function happens before tkinter recognizes the button being mapped, even though it is already gridded. I couldn't find a way to wait for the button being properly mapped before the print function is executed.

from tkinter import *



class fb( Frame ):

    def fastbuttons( self ):

        b = Button(self)

        b.grid()

        print( b.winfo_ismapped() )



    def __init__( self, master=None ):

        Frame.__init__( self, master )

        self.grid( sticky='nsew' )

        self.button = Button( self, text='Start', command=self.fastbuttons )

        self.button.grid()

        

if __name__ == '__main__':

    root = Tk()

    app = fb( master=root )

    app.mainloop()

IDLE in snow leopard

donjones77 — Wed, 16 Dec 2009 03:19:37 GMT

I haven't been able to get my version of IDLE to open
since I upgraded to snow leopard. Is this my unique problem?
Or does snow leopard require a special version of IDLE?

Thanks for any help.

Yet again, one more recursive problem!

johni12 — Wed, 16 Dec 2009 01:29:35 GMT

Hey, I'm sorry for being such a python newb, but thanks for helping me out with the last one! Hopefully you guys will help a newb out again :)

This time, I need to use a recursive function to basically do the same thing that the .replace function for strings in python does. Problem here is, yet again, I have no idea how to attack this problem.

My idea is to maybe shorten the original string by one index with each recursive call and add the replacement string once the old string has been cut out, but the problem is, I don't know how to save any letters prior to the substring to not permanently get rid of the pieces I need to put the string back together with the new string in place of where the old string used to be.

I wish I could provide atleast some sort of code, but I honestly have absolutely no idea how to even start this one, with the exception of the base condition:

if string==""
return

any help would be greatly appreciated! Thank you!

PS a sample run and desired output should look something like this:

% replace_recursion("stringproblem","problem","solution")
% "stringsolution"

Once again, thanks for any input or help! Ideas are appreciated greatly too!

Help! Python problems

HalpMe — Wed, 16 Dec 2009 00:47:03 GMT

Hey Guys, I have a test tomorrow and this question is going to be dead similar to my test question, and I'm a mech.E major but for some damned reason Python is a mandatory course for us. Please if any one could solve this I would be very grateful. Please Help me.

A family unit consists of one guardian and zero or more babies.
A baby has a name and an age.
Define classes for family unit and baby. (You will get more points if you make the data members private.)

All the family unit data are stored in a file named familiartxt. You are guaranteed that this file exists.
In the data file, a family unit is stored on at least one line - the guardian. After the guardian (well actually just the name) there are lines for each baby – their name and their age in parentheses.

Here is a sample data file showing the internal format of the data:

Ralph The Magnificent Mangler
Quizzlechomps (32)
Miki (24)
END REC
Mary the Meek
Middendorf (812)
Muddle (10)
Makrryrlr (232)
END REC
Buster
END REC

Write a function that will return a container of all the family units from this file. The file should be opened and closed in this function.
Write a function to display all the family units in a list of family units in descending alphabetical order by guardian..
Babies must be in the order of youngest to oldest. (This is not necessarily the order they are in in the file.

Finish Part ONE before going on to Part TWO

Part TWO --- Adding and removing babies.
Anyone who has a valid password can change things. A valid password here, is really in the range [33.55] or (457.993].
For now, be infinitely patient with the password entry
Once validated, they can choose to remove a guardian or a baby - but only one at a time – their password will have to validated after each change..

A family unit is chosen at random. The user decides to remove a guardian or a baby. If they choose baby, a random baby under the chose guardian's care is chosen. If they choose a guardian, all the babies under that guardian are also gone.

One of the rules of this world is that no guardians can be removed if their name is the same as a baby under another guardian. Your code must enforce this – just ignore any attempt in this case.

For processing"
Display all the family units and then go through the process of letting people validate their passwords and make changes.
Be sure to show all the family units after each person removes someone.

It's also possible that someone might decide to change the name of a guardian instead of removing them. When a guardian's name is changed, all of the baby under his care have their names changed to the new name also.

There is a special password that allows anyone who knows it to stop processing. When this happens, the number of babies still in the system is displayed (and then the program ends).

Here is a sample run of Part TWO. Remember to solve problems, not examples.
We are using the data shown above to start with.

Recursion help!

johni12 — Tue, 15 Dec 2009 20:12:51 GMT

Hi, I am a newbie here and a python newbie as well :) I am having trouble implementing a program in which you must use only recursive functions and no built-in python functions other than the len function in order to determine if there are duplicates of an item in a given list. The function returns True if there is and False if there isn't. The base condition would be if there is nothing in the list (hence the use of the len function). What I am having trouble with here, is how do you take an item and compare it to the other items in the list to see if they are equal, and if not, discard that item and continue this type of searching? Using only recursive functions? Or is there something else I must do to check for duplicates?

I suppose the general question here would be for example:

Given a list L that is [1,2,3,4,5,1,6], how could I use recursive functions to check if the first index of the list (in this case, 1) is equal to any other indexed item in this list? And if not, discard the first index and make the next index the first index (index 0)? If this is not possible, what is a workaround that provides the result im looking for?

FTP or SSH in python

afireinside7710 — Tue, 15 Dec 2009 19:21:26 GMT

hey guys, first post.

I have a program that takes a file from a windows box, and FTP's it to a unix/linux box. The program works fine, however there is something i want to add to it. I want the program to send 2 commands to the unix box while im still connected to it:

1) a concatonate command [cat MASTERLOGFILE.txt newlogfile >temp] and
2) a copy command [cp temp MASTERLOGFILE.txt].

I have read that there is a ftp.sendcmd(command) command that transfers a command to the box that its connected to, however i get errors when running the above mentioned commands. Is it possible to do this? Should I create a new program that ssh's into the desired unix box and throws commands that way? Thanks for any help!

Thankful for any help!

How do you make sprites appear on top of others?

etypaldo — Tue, 15 Dec 2009 07:51:22 GMT

I am writing a pygame program that has a moving background which is a sprite. I was wondering if/how you can make sprites appear on top of others (some kind of priority in what appears on top of what). I know the order they appear on top of one another is based on which one is added to the screen first but I am wondering if I can change this.

Thanks

Fill In The Blank (Homework help) (urgent)

scrace89 — Tue, 15 Dec 2009 00:30:38 GMT

My teacher gives a review sheet which is a lot like the exam if not the exam but with some minor changes. I'm stuck with these fill in the blanks.

Fill-In-The-Blank       Word Frequency

The following program gets the name of a file as a command-line argument, opens that file, reads from it and creates a dictionary of the words in the file and the number of times each word occurred.

import _______________

import sys



NUM_ARGS = ___________



words = {}



if len(sys.argv) != ______________:

    print "This program needs a command-line argument"

    print "that is the name of the file to evaluate."



    sys._______________





file = open(_______________, 'r')



for line in ____________:



    string.strip(___________)



    _____________  = string.split(line)



    for word in wordList:

        # change word to be in all lower-case

        word = string.lower(word)



        # if the word has punctuation after it

    

        if ord(____________) < ord('a') or ord(____________) > ord('z'):



            # remove the punctuation mark from the word



            word = word[: ___________ ]



        # put the word in the dictionary and/or increment the word counter



        count = words.___________(word, 0)



        words[ ____________ ] = count + 1

        

file.______________



print _____________

this is what I have so far, I have no idea how to fill in the last two blanks.

import string

import sys



NUM_ARG = 2



words = {}



if len(sys.argv) != NUM_ARG:

    print "This program needs a command-line argument"

    print "that is the name of the file to evaluate."

Code Snippet DIY animated desktop

Tech B — Mon, 14 Dec 2009 21:34:56 GMT

Thought someone might like this little script. Its an animated wallpaper.
You'll need to draw the frames though. I used Windows paint to make the frames. I drew two stick people fighting. You'll need to know the basics about animation. I saved each picture as .bmp It worked with .jpg but had a little lag.

The original background will appear upon logging off or shutting down. To avoid this you'll need to use ActiveDesktop extensions. Or put this script in the startup folder.

It can be used as a slide show too, by changing the time.sleep()

Any questions feel free to reply.

Okay, well I've been looking for at least an hour now for some straight-forward python-xlib documentation, and I have been unable to find any. Luckily...I have quite the easy problem.

If somebody would be able to help me create a simple script that would say "Hello" every time the left mouse button is clicked, I have the rest of what I would like to do figured out

This is what I have so far, to no avail:

#!/usr/bin/python



import Xlib

import Xlib.display



def main():

    display = Xlib.display.Display()

    root = display.screen().root

    while True:

        event = root.display.next_event()

        if event:

            print "Hello"



if __name__ == "__main__":

    main()

Thank you so much in advance.

Is there any alternative suggestion to do it?

Help formatting in numpy.loadtxt

RogerI — Sat, 12 Dec 2009 17:30:29 GMT

I need to read in a large amount of data from a csv file into arrays. I am using Numpy as I need to later manipulate and plot the results. I have decided to use numpy.loadtxt as this appears to be the most efficient method to read in the data. I can read the data into one big string array but I am struggling to convert the data as I read it in.
Here is the code I am using...

# -*- coding: utf-8 -*-

Created on Sat Nov 21 21:41:05 2009

"""

import numpy as np



test=np.loadtxt('data_dev_test.csv',delimiter=',', unpack=True,

                  dtype={'names':('localtime','localdate','elapsedtime','dose','units'),

                         'formats': ('s8','s7','s10','.3f','s2')})





print test

And the data has the format...

11:16:29, 24NOV00, 0000:00:00,1.087,nG
11:17:34, 24NOV00, 0000:01:04,1.087,nG

On running the code I get the following error...

Traceback (most recent call last):
File "C:\Python26\Lib\site-packages\xy\tepc.py", line 11, in
'formats': ('s8','s7','s10','.4f','s2')})
File "C:\Python26\lib\site-packages\numpy\lib\io.py", line 443, in loadtxt
dtype = np.dtype(dtype)
TypeError: data type not understood

I'd really appreciate any assistance here as I am farily new to Python and do not know where to go next.

Many thanks in advance,

Okay, this is what I am trying to do. I am attempting to create my own encrypter. I have the base encryption running, used just to encrypt a string you put in. I am going to add functionality to open a text file's contents and encrypt them, outputing them into another text file. I will be working on that later, so I might post up my questions if I can't figure it out. Anyways, this is what I need help with:
1) How do I open a file's binary code, and convert it to hex?
2) After opening it in hex, it shoud become manipulatable, such as, I can make it into a list, then change each odd charecter, correct?
3) After messing with the hex, how do I convert it back into binary, then save it?
Thank you very much in advance!

Python tkinter resize problem

ribot — Sat, 12 Dec 2009 13:14:08 GMT

Hi!
I'm trying to combine some frames in a GUI as a toolbar and content area. Currently I'm on windows and using python 3, and I want preferrably my app to work on *nix and mac as well.

The problem is that in the following app, when I resize it the toolbar area is increasing/decreasing, and the content area is staying the same. I would like the opposite to happen. In other words, the area with the 'up' button shouldn't be resized, but the area with the 'down' button should.

My reasoning is that since the lower area, b, is using a sticky in all directions, and the upper button is sticking north, so the lower area should be resized.

Thanks for your help!

from tkinter import *



class app( Frame ):

    def __init__( self, master=None ):

        Frame.__init__( self, master )

        self.grid( sticky='nswe' )

        self.top = root.winfo_toplevel()

        self.top.rowconfigure( 0, weight=1 )

        self.top.columnconfigure( 0, weight=1 )

        self.rowconfigure( 0, weight=1 )

        self.columnconfigure( 0, weight=1 )

        a = Button( self, text="up" )

        a.grid( row=0, column=0, sticky='n')

        self.b = Canvas( self, bg='black' )

        self.b.grid( row=1, column=0, sticky='nswe' )

        c = Button( self.b, text="down" )

        c.grid( sticky='nswe')

        d = self.b.create_window( 10, 10, window=c, anchor=NW )

if __name__ == "__main__":

    root = Tk()

    appl = app( master=root )

    appl.mainloop()

How to 'refresh' in wxPython?

Hey All,

I have 'Py-mailer' here.... here's how it is so far:

import smtplib

import wx



window=wx.App()



class pymailer(wx.Frame):

    

    def __init__(self):

        wx.Frame.__init__(self,None,-1,"Py-mailer",size=(900,700))



        self.panel=wx.Panel(self,-1)



        menubar=wx.MenuBar()



        filem=wx.Menu()

        filem.Append(201,"Quit")

        self.Bind(wx.EVT_MENU,self.Quit,id=201)



        viewm=wx.Menu()

        viewm.Append(202,"About")

        self.Bind(wx.EVT_MENU,self.About,id=202)



        menubar.Append(filem,"File")

        menubar.Append(viewm,"Help")



        self.SetMenuBar(menubar)



        wx.StaticText(self.panel, -1, "Login ID:", pos=(10,10))

        wx.StaticText(self.panel, -1, "Password:", pos=(10,40))



        self.username=wx.TextCtrl(self.panel,101,"Login ID",pos=(100,10))        

        self.password=wx.TextCtrl(self.panel,102,"Password",style=(wx.TE_PASSWORD),pos=(100,40))



        wx.StaticText(self.panel, -1, "@gmail.com", pos=(220,10))



        login=wx.Button(self.panel,103,label="Login",pos=(115,70))

        self.Bind(wx.EVT_BUTTON,self.Login,id=103)

        

        wx.StaticText(self.panel,-1,"To:",pos=(10,120))

        wx.StaticText(self.panel,-1,"Subject:",pos=(10,150))

        wx.StaticText(self.panel,-1,"Message:", pos=(10,180))



        self.to_info=wx.TextCtrl(self.panel,104,pos=(80,120),size=(300,20))        

        self.sub_info=wx.TextCtrl(self.panel,105,pos=(80,150),size=(300,20))        

        self.msg_info=wx.TextCtrl(self.panel,106,pos=(80,180),size=(800,400))

        

        send=wx.Button(self.panel,107,"Send",pos=(400,600))

        self.Bind(wx.EVT_BUTTON,self.Send,id=107)



        self.Centre()

        self.Show()



    def Quit(self,event):

        self.Close()

    

    def About(self,event):

        about=wx.AboutDialogInfo()

        

        about.SetName("Py-Mailer")

        about.SetCopyright("(c) 2009 Sravan and Daniel")

        about.SetWebSite("http://www.team-vaska.co.cc")

        about.AddDeveloper("Sravan")

        about.AddDeveloper("Daniel Pacheco")



        wx.AboutBox(about)



    def Login(self,event):



        self.user=self.username.GetValue()

        self.passw=self.password.GetValue()

        self.loginmsg=wx.StaticText(self.panel,-1,"...",pos=(10,200))



        if(self.user=="" and self.passw==""):

            wx.MessageBox("Error 002: You did not enter your username and/or password","Enter Login Details")



        try:

            self.s.login(self.user,self.passw)

            self.loginmsg.SetLabel("Logged in...")

        except:

            self.loginmsg.SetLabel("Failed to login, please try again...")

        



    def Send(self,event):

        self.to=self.to_info.GetValue()

        self.subject=self.sub_info.GetValue()

        self.message=self.msg_info.GetValue()

        self.msg="To: "+self.to+"\nSubject: "+self.subject+"\n"+self.message

        self.s.sendmail(self.user,self.to,self.msg)

        self.s.quit()        



        wx.StaticText(self.panel,-1,"Your message has been sent!",pos=(175,500))        



pymailer()

window.MainLoop()

Now what I want to do is: when the user clicks the "Send" button, the panel should refresh, and only a StaticText should be displayed in the centre saying "Sending...". After that I should say (after the message is sent) "You message has been successfully sent to _____".

How do I make the panel destroy all it's contents?

Thanks,
Sravan

Equal probability problem

takarii — Sat, 12 Dec 2009 00:33:12 GMT

Ive written a program to do with drawing a line from a centre point and it is meant to snake randomly from the centre.

However, it seems to be incredibly biased as to where it decides to go.

the 4 directions are as simple as up down left and right, but it seems to only really head upwards. Yet i can see that some of the numbers do infact tell it to snake downwards, however it seems to make no real difference.

Any suggestions? (I do know there is some redundant code in there, but ill preen that later on.)
