How do I set up a C extension for Python?

To set up a C extension for Python, you'll need to create a C file, write your functions, and then compile it using a setup script.

What does the setup script look like?

The setup script typically uses the setuptools module. Here's a basic example:

from setuptools import setup, Extension

module = Extension('my_module', sources=['my_module.c'])

setup(name='MyModule', version='1.0', ext_modules=[module])

How do I compile the extension?

You can compile the extension by running the command python setup.py build in your terminal.

Can I use this extension in my Python code?

Yes, once compiled, you can import your C extension in Python just like any other module using import my_module.
