Can you please explain how setup.py and distutils work?

Question

Python

If I understand correctly, then distutils is a module that allows you to build your own modules, so that in the future people can install them with the usual line "pip install ...", and setup.py is a python file that just produces this a simple Installation? Did I understand everything correctly or not, please explain.

Answer 1

Not really. setup.py is more of a file that describes your package so that distutils knows how to install it, what dependencies it has, who the author is, what are the entry points, and so on.
Here is an excellent article on Habré how to make the perfect package: https://habr.com/ru/post/483512/
