Another option might be to wrap your C code using the ctypes module (
http://starship.python.net/crew/theller/ctypes/). This might be especially attractive if this code is mostly for demo purposes (at least for demo purposes on win32). Ctypes basically allows you to call C code from python, but rather than handling the data type translations in C (like in a "normal" extension), you handle the translations in Python.
For C++ code you might check out boost.python. I haven't used it but I've heard good things.

Hi Chris,
I would recommend buying Visual Studio. It's what python 2.4 is built
with, and it makes compiling extensions nice and easy.
My favorite examples of extending python include:
- screengrabber extension for the python imaging library
http://effbot.org/downloads/
1) download and install the Python imaging library (PIL)
2) download the screengrabber source and uncompress to a directory.
3) look at the _screengrab.c (or whatever it is called) to see how it
accepts and returns python argumetns, but does win32 calls inbetween.
4) run " python setup.py build " to invoke Visual C++ (or mingw if detected.)
5) run " python setup.py install " to try it interactively.
- My second favorote example is on the wxPython Wiki, it shows how to
extend wxPython with commercial VC++
http://wiki.wxpython.org/index.cgi/C%2B%2BExtensions
I wrote the pages for VisualStudioExtenions and SconsExtensions, so
let me know if you need them to be more helpful. I wrote them
hastily, but I think I got the important parts right.
