input is a built in function that only needs a string and gets input from the user. There are a few other things that dont work in your program, like print w*random will just times w by random and give back one number, here is a sample of what i think you mean to do
import random
exit = False
while not exit:
nums = input("how many numbers?")
for f in range(nums):
print random.randrange(0,100),
That will give you the amount of numbers you want, ill leave the exiting for you to figure out.
But do you see how this works? I get the user input of how many random numbers and then i loop through that many times and print out a random number between zero and one hundred. Then that gets printed out.
There are a few problem is see with your doc. Firstly this one: >>> count('ana', 'banana') 2 there is only ONE ana in banana, the other one is a cross over of it, so in that case you should have >>> count('ana', 'banana') 1 as your docstring.
Also your function is wrong, it will only ever get one as a return value at max, that is because an if statement executes and then goes on. This seems like a more relevant function.
def count(string, sub):
return string.count(sub)
See how that goes, and ill help out if there is something still wrong with it.
Just a thought, i cant see how it breaks out of the loop, so maybe move the other raw_input() in a bit:
# -*- coding: iso-8859-15 -*-
# check encoding in http://www.python.org/dev/peps/pep-0263/
def function1():
print "Bonjour, comment allez-vous ?"
def function2():
print "Hola, cómo esta usted?"
def function3():
print "Hello, hoe zijn u?"
def function4():
print "Hallo, wie geht es Ihnen?"
#main
print "Hello, how are you?"
while True:
choice = raw_input("Enter a language (french, spanish, greek, german): ")
if choice == "french":
function1()
elif choice == "spanish":
function2()
elif choice == "greek":
function3()
elif choice == "german":
function4()
else:
print "You have to choose from french, spanish, greek or german!"
if raw_input("\n\nPress the enter key to exit.") == '':
break

running = True
sent = raw_input("Enter a sentence")
while running:
for word in sent.split():
if word[0] in "aeiou":
print word + "way"
else:
print word[1:] + word[0] + "ay"
What i did was ask for a sentence at the start and then i split it into words using the sent.split() function, then i could do the whole sentence at once rather then one word at a time.
import wx
import wx.lib.scrolledpanel as scrolled
class TestPanel(scrolled.ScrolledPanel):
def __init__(self, parent):
scrolled.ScrolledPanel.__init__(self, parent, -1)
vbox = wx.BoxSizer(wx.VERTICAL)
desc = wx.StaticText(self, -1,
"ScrolledPanel extends wx.ScrolledWindow, adding all "
"the necessary bits to set up scroll handling for you.\n\n"
"Here are three fixed size examples of its use. The "
"demo panel for this sample is also using it -- the \nwxStaticLine "
"below is intentionally made too long so a scrollbar will be "
"activated."

I see a problem here. Firstly have a look at the start, there is an ' mark, this makes the value of resource a string forever and no dictionary. So resource equals all this:
import os
path = "path here"
seconds = os.path.getmtime(path)
print time.strftime('%Y-%m-%d %H:%M', time.localtime(seconds)
#it will output the time last modified!
something is wrong with the actual dictionary, when i put it into python i get errors along the lines of SyntaxError: EOL while scanning single-quoted string
and i tried for a few minutes but i couldnt get it to work, the "" marks were all out of place.
Well my next and last step would be to go to the wxpython mailing list and see if anyone there can help, i find if there is ever a problem in wx that cannot be fixed, that the mailing list really does the trick.
Yeah i got the same issue when i did a program using a richtextctrl. I fixed it by binding the delete key to an event where i called something along the lines of
I remember having to bind it to a wx.EVT_KEY_DOWN event because i could not find one for DELETE specifically so then i just checked in the method to see if it was the delete key and then if it was the method continued to run.
And you can add to things as well and change things around. So you can have a class of Line, that has:
Attributes start end
And if you wanted to make box, well a box is just a complicated set of lines, so if you inherit from lines then you already have some stuff sorted out, though you can overwrite anything in lines by redefining it in box.
So box could have
Attributes list_of_lines area curcumference
And then you can have a cube, which is just a number of boxes joined together, i guess i should have called box square huh? BUt it means that when making the cube you do not have to worry about lines, they are already dealt with, you do not worry about the squares being put together, they are already working, so all you have to do is work out the arrangement of the squares.
Classes generally are there and tend to (if used well) make your job a lot easier.
Just press space 4 times, then you have it indented the right amount. Do this for all of them, not the actual if statement but the stuff afterwards. So
>>>if stuff == True:
... print "stuff" #i pressed space 4 times
... else:
... print 'no'
word = "Hello"
for letter in word:
#this iterates through every letter in the variable word
#and to check if A in B then
a = "1"
b = "123"
if a in b:
#this will be tru, a is in b
Ah the value is False. Does that mean that curtains will not work unless you are using something like Vista? Or is there some way that i can make it work on XP?
So at the end of my loop i gave you you need to reconstruct the sentence so find a way to peice it back together. Here is a code snippet which might help:
first = "hello"
second = ""
for letter in first:
second += letter
print second
#prints "Hello"
And what you need to do, is if that for every time through the loop you check to see if the letter is a vowel, if it is then the if statement will be true and run, so then you would have to use that letter= letter.upper() code and that would capitalize your letter ready to be added onto the second string.
Woops silly me, i didnt download the .exe installer. Okay well its installed now.. But im at a loose end.. Can you tell us how we would be able to test the taskdialog. Because my current code:
#testing Curtains
import curtains
def tester(event):
print "hello"
f = curtains.TaskDialog("Hello",'World',"Please do smething", "retry")
f.bind(curtains.BUTTON_CLICKED,tester)
f.show()
This raises an error: NameError:global name 'indirect' is not defined Line 8 in module: f.show() Line 307 in show: indirect(byref(conf), byref(button), byref(radio), byref(checkbox)
So if there is something i am doing majorly wrong just post it. It would be lovely to just post a simple example of a working taskdialog.
Okay, well not to fully solve the problem for you i would do something like this:
S = raw_input("Enter a sentence:")
vowels = 'aeiou'
for letter in S:
if letter in vowels:
#letter is a vowel
letter.upper()
Now that does nothing at all, just shows you an idea, what you need to do is have another variable and add the letter to it each iteration of the loop.. see if you can do that yourself.
If you have any questions about how this works just post!
Okay, i see you are using wing IDE, well in that case go to stack and go to the Call Stack, Click on them one by one and at one of them you will get something do with the actual problem, not just the function that called the problem.
So tht way you will be able to give greater detail as to whats going on.
Well can you post the whole error because that usually also shows what line it is on, it makes it easy to debug. But ill give you an example of something that would get that error:
f = open("infile.txt")
f() #here i would get my error. The file variable is not callable
f.close()
Yeah i can help a bit as well... maybe a bit slow.. i have a broken computer and i am left with using an old decrepit computer from years and years ago
Personally i never use GUI builders, i just code from scratch, it leaves you learning a lot more about the code and how it works and stuff like that, so in my opinion its best to just learn how to write the code
Okay, so a vector is basically a direction of where to go with a velocity. I think... Okay, well i don't think there is more to be learnt so i will mark this as solved. Thanks for the help guys.
Hmmm... i sortove get it, what is the point of having whole classes devoted to vectors though, it seems a bit over the top if its just the position and velocity of something, is there something deeper i do not understand here?
