You would either need to wrap your C file as a Python module. Docs are
available here http://docs.python.org/extending/extending.html

Or you can compile your C file into a library and use the ctypes FFI
The docs are fairly descriptive and have an included tutorial as well
http://docs.python.org/library/ctypes.html
