The best thing to do is to offer your C++-lib with a C-style interface. 
Then you can use python's ctypes (included since python2.5) to access 
the shared library.

If you insist on using C++, you can expose the lib using several 
available wrapper generators. I know of three: SIP, Swig & 
Boost::Python. The first I've got some very good first-hand experience. 
The second is somewhat primitive IHMO. The third I never used.

Use these to google in this group, you'll find plenty of stuff.
