If you have a windows machine, you can achieve accuracy better than 1 millisecond with time.clock() ... [code=python]# time.clock() gives wallclock seconds accurate to at least 1 millisecond # it updates every millisecond, but only works with windows # time.time() is more portable, but has quantization errors # since it …

I borrowed this from C#, where you can easily send output, that normally goes to the ugly black console window, to a nice looking Windows MessageBox with an OK button to close after you read your results. You can accumulate your output in a string to send to one message …

My answer to the large volume of mostly political robo calls has been the answering machine. I will call back any friends.

Here would be one approach ... # Python27 # create two different test sets list1 = list('abcde') list2 = list('acdef') set1 = set(list1) set2 = set(list2) print(set1) print(set2) ''' set(['a', 'c', 'b', 'e', 'd']) set(['a', 'c', 'e', 'd', 'f']) ''' match = True # now iterate through set1 and print …

Line 7 needs an extra **]** at the end line 8 needs to be **else:** Are you sure you want **&** rather than **and**

Or you can modify this old code to suit your needs ... # input a sequence of integer numbers separated by a space and convert to a list # works with Python2 or Python3 try: input = raw_input except: pass def get_integer_list(): while True: # get the sequence string and …

With Python's builtin module sqlite3 you have a CREATE TABLE IF NOT EXISTS command ... # explore Python module sqlite3 # create a database file # query language in upper case (optional) import sqlite3 import os # create/connect to a permanent database file file_name = "stock_portfolio1.db3" con = sqlite3.connect(file_name) # …

It might be time to use the editor environment that comes normally with your Python distribution. Since you are using Python26 try this batch file ... C:\Python26\pythonw.exe -u C:\Python26\Lib\idlelib\idle.pyw Otherwise you have to give the full file path in your commandline. That does get tiresome.

This might help you ... import random def difficult_menu(): print("""Difficulties: 1.) - Easy 2.) - Medium 3.) - Hard""") return int(raw_input("Choose a difficulty: ")) def type_menu(): print("""Types of Math: 1.) - Add 2.) - Subtract 3.) - Divide 4.) - Multiply""") return int(raw_input("Choose one of the choices:")) def pick_random_integer(difficulty): # …

Now remember that raw_input will give you a string.

This snippet explores the change of a hexadecimal (base 16) string to a denary (base 10) integer and the reverse. Interestingly Python allows the representation of the hexadecimal string in two different forms. For instance 255 can be changed to 'FF' (also 'ff') or '0xff'. Any of these hexadecimal strings …

Here is an example how to connect a button to a label ...

Our friend Gribouillis has a masterful solution. Let's just hope nobody at the job interview asks you to explain how it works.

Actually there are many ways to solve this, but here would be an example for a beginning student. Study it and try to understand it ... [code=python] a = [4,5,6] b = [1,3,8,6,7,9] c = [] for bx in b: if bx in a: c.append(bx) if c: print "these are …

Let's assume you want something like this ... [code]import pprint # create a dictionary of keys a to z and zero values d = dict([(chr(k), 0) for k in range(ord('a'),ord('z'))]) #pprint.pprint(d) # test # the test sentence s = "Albert has many marvelous attributes" # convert to all lower characters …

You might want to use os.listdir(directory) ... [code]# list filenames in a given directory import os # assign a directory name for test directory = "C:/Python27/Atest27/Bull" # os.listdir(directory) creates a list of filenames in directory #print(os.listdir(directory)) # test # test print the list one filename each line for fname in …

[php] // how many elements can a vector hold? // a huge number, actually until memory runs out! // well, let's test it to a million elements ... vector<int> kV; cout << "loading an integer vector with numbers 0 …

Your example is really not stupid! Remember, even the best of us were stupid about Python at one time ... [code=python]a = 0 while a < 10: a = a + 1 if a == 4 or a == 6: # create file for instance 'output4.dat' # only strings concatinate …

Just one idea how you do this ... [code]# toggle a Tkinter button up/down # using images and no button border # tested with Python 2.7 and Python 3.2 by vegaseat try: # Python2 import Tkinter as tk except ImportError: # Python3 import tkinter as tk def action(toggle=[True]): """ toggle …

Python does a lot more hand-holding than C or C++ when it comes to those pesky memory leaks. Like C++ Python is object oriented.

You could import your frame2 file into your frame1 code and instantiate it there.

The code shows a fast prime number generator using a sieve algorithm. It looks at only odd numbers. Technically 1 and 2 are prime numbers too, since they are only divisible by unity and themselves, exceptions are made for 1 and 2. Zero and negative numbers return an empty list. …

There are servers that have Python installed, but I never heard of one that also has wxPython installed.

With the Tkinter GUI toolkit there a several ways to layout the position of the widgets. Here is an example of an absolute place layout ... [code]# set position and size of a Tkinter window # also set the position of any widgets using place(x, y) layout try: # Python2 …

You need to show us some coding effort.

Example ... [code]# two ways to represent integer 1234 as a hexadecimal number # 0x is the official prefix for a hexnumber # the results appear different, but both are of type string # and change back to base 10 properly # tested with Python27 n = 1234 # using …

The ultimate Zen.

You can try: [url]http://pyopengl.sourceforge.net/[/url] Also the wxPython GUI toolkit has OGL pretty well integrated ... [code]# the Open Graphics Library (OGL) is now pretty well # integrated with wxPython import wx import wx.lib.ogl as ogl class MyFrame(wx.Frame): def __init__(self): wx.Frame.__init__( self, None, wx.ID_ANY, "wx.lib.ogl Demo", size=(400,300)) canvas = ogl.ShapeCanvas(self) canvas.SetBackgroundColour("yellow") …

Take a look at a typical Windows GUI frame (form) with a menubar, statusbar, panel, label and buttons. Set the font and size of text, click the buttons to create some events. All of this and much more is in the free wxPython package.

UTF8 is pretty much the defacto standard for decoding in Python. However there may be other standards on the internet, depending on the country and its native language. In this particular case ( [url]http://www.python.org[/url] ), you can find the encoding used in this line: [code] <meta http-equiv="content-type" content="text/html; charset=utf-8" /> …

Computers make mistakes! It's not on purpose.

Programming without Google? Hard to imagine!

It is important to use command argument 'build' Run the build process by running the command: python makeexe.py build

Version 2.6 of wxPython has support for playing animated gif image files. The example sets up a panel on a frame and then uses wx.animate.GIFAnimationCtrl() to do the hard work. Actually pretty simple code.

Mark, I think it is just a very specialized area. I did a lot of that kind of work in my earlier days using Delphi and the RS232 serial port. The modules (ADAM from Advantech Co., Ltd.) I used exchanged data as strings. It worked very well and was fun! …

You can expand that with slicing ... [code]# using del and slicing on a list ar = range(7) print ar # [0, 1, 2, 3, 4, 5, 6] # delete element 1 and 2 del ar[1:3] print ar # [0, 3, 4, 5, 6] ar = range(7) # delete every …
