Extending Python

[Tuvas]

I am looking for a good tutorial on how to extend python with C code. I
have an application built in C that I need to be able to use in Python.
I have searched through various sources, starting of course with the
Python site itself, and others, but I felt a bit lacking from the
Python site, it seems it was only made for those who installed the
source distribution, as for the other people... Anyways, thanks for the
help!
