Is google dead today?

First hit.

Ctypes is a since python2.5 built-in module that allows to declare
interfaces to C-libraries in pure python. You declare datatypes and
function prototypes, load a DLL/SO and then happily work with it. No C, no
compiler, no refcounts, no nothing.

And you can pass python-functions as callbacks.

See the module docs for examples.
