distutils is a python module that comes built-in with python, and it simplifies the process of building and distributing python extensions or packages. in this tutorial, you will learn how to install a python extension module using distutils, which is a fundamental skill for python developers who need to distribute their code as a package or extension.
before we begin, make sure you have the following prerequisites:
python: you need to have python installed on your system. you can download python from the official website.
a c/c++ compiler: to build python extension modules, you'll need a c/c++ compiler installed on your system. on linux, you can use gcc, and on windows, you can use microsoft visual c++.
setuptools: while distutils is part of the python standard library, it's common to use setuptools, which is a more feature-rich and flexible package distribution library built on top of distutils. you can install setuptools using pip:
let's create a simple python extension module to demonstrate the installation process using distutils. in this example, we will create a module that calculates the factorial of a number. the extension module will be written in c and compiled to a shared library.
step 1: create a directory for your project:
step 2: create a python source file (factorial.py):
step 3: create a c source file (factorial.c):
step 4: create a setup.py script:
now that we have our extension module, we can build and install it using distutils. make sure you're in the same directory as your setup.py script.
step 5: build and install the extension module:
this will compile the c code and install the python extension module into your python environment.
you can now use your installed extension module just like any other python module. here's an example of how to use it:
that's it! you've successfully created, built, and installed a python extension module using distutils. you can distribute your extension module as a package or share it with others who can easily ...
