I have two custom-written C routines that I would like to use as a part of a large Python application. I would prefer not to rewrite the C code in pure Python (or Cython, etc.), especially to maintain speed.
What is the cleanest, easiest way that I can use my C code from my Python code? Or, what is the cleanest, easiest way for me to wrap my C code for use in my Python source?
I know "cleanest" and "easiest" will attract opinions, but I really just need some good options for using custom pre-written code, versus many of the other answers/tutorials which describe how to use full-on C libraries as CPython extensions.
EDIT:
Cython and ctypes have both been suggested. Which is a better choice in my case? Each of the two routines I mentioned originally are very computationally intensive. They are used for image calculations and reconstructions, so my plan is to build a Python application around their use (with other functionality in mind that I already have in Python) with the C code run as needed for processing.
Use cython to wrap your C code. In other words, create a CPython extension using Cython, that calls your C code.
