- Python can interface with C code using the built-in ctypes library, but ctypes is notoriously clunky. The third-party CFFI project offers a more streamlined way to build interfaces between Python programs and C libraries.

What are Python bindings? Should you use ctypes, CFFI, or a different tool? In this step-by-step tutorial, you'll get an overview of some of the options you can use to call C or C++ code from Python.
Mar 9, 2013 · ctypes is a Python wrapper around libffi. The CPython project carries a version of libffi with it, and ctypes consists of a C extension module linking to libffi and Python code for the required glue. If you understand how to use libffi, it should be easy to see how ctypes works.
Jul 19, 2013 · I'm being told at pyconuk this week that using cffi is nowadays faster than using ctypes, especially for applications like OpenGL where you're constructing arrays of C types and then frequently modifying slices of them and re-sending to the C drivers.
Sep 15, 2018 · CFFI is Python with a dynamic runtime interface to native code. cffi then is the dynamic way to load and bind to external shared libraries from regular Python code. It is similar to the ctypes module in the Python standard library, but generally faster and easier to use.
1 day ago · For example, if your use case is calling C library functions or system calls, you should consider using the ctypes module or the cffi library rather than writing custom C code. These modules let you write Python code to interface with C code and are more portable between implementations of Python than writing and compiling a C extension module.
Sep 3, 2019 · Then we will write the computationally heavy part of the code in C, and learn how to call it from Ctypes (part of the Python standard library), CFFI (a newer and better Ctypes alternative), Cython (a compiler from Python to C), and CPPYY (like Ctypes and CFFI, but for C++).
How to use Python’s built-in CFFI module for interfacing Python with native libraries as an alternative to the “ctypes” approach. In previous tutorials, we covered the basics of ctypes and some advanced ctypes usage. This tutorial will cover the CFFI module.
