I'm very new to python, as i'm embedding it (in form of a static lib) in an ios project. It's not possible for me to dynamically load python modules, so i would like to compile my modules along with python.
For modules shipped with the python source this works (by modifying setup.py or Module/Setup), but when i downloaded a third party module i noticed, i don't fully understand the mechanism.

The modules shipped with python come with a .c file in the Modules dir as well as a .py file in the Lib dir.
My third party module just comes with .py files.

1.Why do those modules have different file extensions?
2.How to integrate a module coming with .py files in an embedded python version? Obviously pasting them in Modules/Setup does require some .c files.
3.Do these .c files have something to do with the Python C-Api?

I guess i'm missing something essential :) Help is much appreciated.
