Please post your question to the Python users mailing list: python-
list@python.org -- mirrored as the comp.lang.python newsgroup too.
Also, gmane.org provides a web interfase: http://dir.gmane.org/
gmane.comp.python.general

Back to your question, the easiest way would be to define a C interfase 
(not C++) that you can call directly from Python using the ctypes 
module (available in the standard library since 2.5)
Another good alternative is to use Cython (which evolved from the Pyrex 
project). See http://wiki.python.org/moin/
