Python Testing with pytest

Creating an Installable Module

We’ll start by learning how to make a small project installable with pip. For a simple one-module project, the minimal configuration is small. I don’t recommend you make it quite this small, but I want to show a minimal structure in order to build up to something more maintainable, and also to show how simple setup.py can be. Here’s a simple directory structure:

some_module_proj/
├── setup.py
└── some_module.py

The code we want to share is in some_module.py:

appendices/packaging/some_module_proj/some_module.py

def some_func():
    return 42

To make it installable with pip, we need a setup.py file. This is about as bare bones as you can get:

appendices/packaging/some_module_proj/setup.py

from setuptools ...
