The best way would be to write something in C that exposes the API to
Python. Check out the docs on "Extending and Embedding Python":

For Python 2.x: http://docs.python.org/extending/
For Python 3.x: http://docs.python.org/py3k/extending/

You'll need to learn Python's own API, of course, but if you're a
competent C programmer, you should find it fairly straightforward.

There's an alternative, too, though I haven't personally used it. The
ctypes module allows you to directly call a variety of C-provided
functions.

http://docs.python.org/library/ctypes.html
http://docs.python.org/py3k/library/ctypes.html

The resulting code isn't nearly as Pythonic as it could be if you
write a proper wrapper, but you save the work of writing C code.
