Chicken nuggets with beer.

Something only Microsoft could dream up. I understand that in the European version of Windows the space is avoided. The kludge itself is from a programmer within Microsoft.

A very simple way:
# create a string where the index gives the grade
grade_str = 'F'*60 + 'D'*10 + 'C'*10 + 'B'*10 + 'A'*11
# ask for grade number input
grade = int(raw_input("Enter the student's...

This is often referred to as the little-known "Microsoft kludge"

You can concatenate tuples, the trick is to wrote the one element tuple correctly:
users = ('user1','user2','user3')

# from input ...
new_user = 'user4'

# concatenate tuples, notice the way...

This problem has been around for a long time and not just with Python:
# the "Microsoft kludge", quoting a string within a string fixes the
# space-in-folder-name problem, tells the OS to use the...

That is because I made a test file from your posting and put it into the working directory, the same directory the code file is in.

Since you have the real thing you can replace
fname =...

Those modules are often written by instructors in colleges to keep their students from simply copying existing code, spreading confusion for the rest of us! There is a similar module out called...

It easier to make fun of something you don't understand, than trying to understand it.

For instance a frequent phrase used by US politicians:

"Dutch treat" in Holland is
"op zijn Amerikaans"
("in an American way")

Don't get even!
Get odd!

Did you use the .msi binary installer to install Python?

How are you trying to open python.exe?

Normally you find the IDE called Idle.pyw somewhere in the Python folders (like...

cTurtle.py has nothing to do with C. It is simply someones hack of the turtle.py with a few extra methods added. See the beginning of file cTurtle.py for details. You can also run it, as it has a...

Try something like this:
label = list(range(len(files)))
for k, fname in enumerate(files):
image = Image.open(filedir+"/"+fname)
##((width, height))
...

You could take each labelobject an append it to a list.

Try something like:
lineA = fin.readline()[lpa].strip()

See if something like this will do, but be careful that all the slicing doesn't steal some data:
def extract_number(data_str):

Also in Python3 'pg_r' would be a byte string and module re will complain without converting 'pg_r' to a string first.

self.panel everywhere except the most important line 12

panel=wx.Panel(self,-1)
needs to be
self.panel=wx.Panel(self,-1)

Are you sure you posted in the right place? This is not the Mindreader Forum!

Hint:
Looks to me like you are creating the same label over and over again.

You don't need the id as a method parameter, but at least try to match the id in the lines above, 202 is not the same as 302.

self.panel will work if you use it throughout the class! Search for...

Pythons normally don't come with a handle, this must be a new breed.

In this case you have to set a flag like this:
import sys

# there is a commandline
if len(sys.argv) > 1:
mylist = []
# sys.argv[0] is the program filename, slice it off
flag =...

Give this a try:
import sys

# there is a commandline
if len(sys.argv) > 1:
mylist = []
# sys.argv[0] is the program filename, slice it off
for element in sys.argv[1:]:

There is another Python version called IronPython that uses Python syntax. It runs independent from the normal CPython version and allows access to the large GUI libraries of .NET and Mono. Here is...

You can trap error details this way:

You can also check into the use of the PyQT GUI toolkit. It is available free and even works with Python 3.1. There is an example here that should work with your application:...

I don't think it's possible because py2exe does not include any source, only the byte code compiled files in case you go for the zip file option.

It's not quite as simple!

However you use Portable Python. It installs a portable version of Python right on an inexpensive USB flash drive (plan on 150MB for each version). You can use the flash...

FYI,
upper = list(string.ascii_uppercase)

Give us your code and we will help you understand.
For instance:
def myloop():
for x in range(5):
y = 2*x
return y

# this will give 8, since the last x in the loop was 4...

Take a looky here:

Thanks vegaseat for the newer PyQT style info. Here is a relatively simple way to display tabular data using a function to create an html coded table:

Sometimes it's nice to have static variable in a function. A static variable remembers its last value. Here is one way to do it with Python:

Have you ever wondered what 'self' is doing when you use Python classes? Here is the short and sweet of it:
# role of self in Python classes
# self can be named different, but 'self' is convention...

Look over this code sample, it should be very explanatory:
# role of self in Python classes
# self can be named different, but 'self' is convention

class Snake:

Ouch! Thanks Lingson, I overlooked that range() does not return a list in Python3. So I give you the correct version here:
