Package Python Code the Hard Way

You have Python code to publish. First, create, and setup.cfg,, pyproject.toml… What are all these stuff? Python packaging is so confusing! In this talk, we are going to throw all them away, and build a package from the ground up.

Python packaging is not hard. Shocking, I know, but it’s true. An installable Python package distribution consists of three parts:

  1. Things you want to distribute (you already have them).
  2. “Core metadata” that describe what you want to distribute.
  3. A file format to bundle the above.

This excercise walks through the process of making a Python package distribution. By doing this, we can have a better idea not only how things are, but more importantly, why they are, and understand why different packaging tools need you to set up certain configurations, and learn to draw analogies when you need to make changes.
