About:
C Foreign Function Interface for Python. CFFI provides a simple and powerful mechanism for interfacing Python code with C libraries. It allows you to call C functions directly from Python and access C data structures, enabling high-performance integration with existing C codebases.

Key Features:

ABI-level and API-level interfacing
Supports C99 and C11 standards
No need for wrapper code generation
Works with both CPython and PyPy

Use Cases:

Wrapping existing C libraries for Python use
Improving performance by calling C functions from Python
Accessing low-level system interfaces

Alternatives:

ctypes – ctypes is part of Python's standard library, while CFFI offers better PyPy support and a more Pythonic API
Cython – Cython compiles Python-like code to C extensions, while CFFI focuses on interfacing with existing C libraries
