Johnny,
look no further than your harddrive.
The Python Standard Lib is full of code examples of Python programming
for various uses.
Just find where your packagemanager has installed them; within windows
it is usually
python24/lib
or
python25/lib
I suspect them to be below usr/lib on linux.
btw... the statement with "youtube" was a joke.
I really applaud rzed you for giving this detailed descriptions,
people like him make the spirit of c.l.p.: People get help here WAY
over what commercial support usually gets you.
Thanks for doing that, rzed!
