There is no standardized C++ API for Python, only a C API :-( There are several
tools that help wrapping a C++ class for Python, however. The one I like most
is the Boost.Python library (http://www.boost.org/libs/python/doc/index.html).
Exposing a C++ class to Python is as easy as it can get with this one.
I can imagine though, that building the library can be a bit problematic. But
they have a mailing list where you can ask for help. (if you use Linux, I can
send you an RPM I have built; I have also built the library on Windows with the

The Boost.Python library contains docs and examples that show its features. You
can even throw exceptions in C++ and catch them in Python. Just to wet your
Perhaps it's also not a bad idea to look into how to do it the old-fashioned
style in C. The standard Python documentation has a chapter "Extending and
Embedding" that briefly tells how this works. For source examples, you can look
into the Python sourcecode itself (the Modules directory).
