Python C interoperability

c, interop, python

Solution

go with Ctypes, it is part of standard distribution and works very well. basically you can wrap C structures and types in python classes, as well as functions. Some types and functionality is already provided by library.

ctypes

couple caveats though: passing triple pointers to C routines is not obvious (if you have to), and I could not get it to work with static libraries on Linux, DLL and shared objects are fine.

Problem

I wish to wrap an existing C (pure C that is. No C++) library into Python so that I can call it from Python scripts. Which approach among the various available (C Api, SWIG etc.) would be the most suitable?
