There are several ways to extend Python’s capabilities. One is to write Python modules in C or C++. This process improves performance and better access to C library functions and system calls. In this tutorial, I’ll show you how to use the Python API to write Python C extension modules. This is all about Cpython.

You will learn through this tutorial

Execute C functions inside Python
You pass arguments through Python to C and parse them in turn
Throw an exception from C code and create a custom Python exception in C
Define global constants in C and access them in Python
Package and distribute Python C extension modules

Expand your Python program

A lesser-known but very powerful feature of Python is its ability to call functions and libraries defined by compiled languages such as C or C++, extending functionality beyond Python’s built-in features. There are many languages you can choose to extend Python’s functionality, so why C? Here are some reasons to build Python extension modules in C:

One of the ways to implement new built-in object types is that Python’s underlying object is implemented in C, and that we can instantiate and extend the class from Python itself.
Calling C library functions and system calls Many programming languages provide interfaces for the most commonly used system calls, though there may be other, less used system calls that are only accessible through C. An example is the os module in Python.

To write Python modules in C, you need to know the Python API, which defines the various functions, macros, and variables that allow the Python interpreter to call your C code. All of these tools and many more are packaged in the Python.h header file.
