Anatomy of a Python Package

2014-01-27 23:00

Over the course of several past months and years I was coding in Python, I’ve created quite a few Python packages: both open source and for private projects. Even though their most important part was always the code, there are numerous additional files that are necessary for the package to correctly serve its purpose. Rather than part of the Python language, they are more closely related to the Python platform.

But if you look for any definite, systemic info about them, you will at best find some scattered pieces of knowledge in various unrelated places. At worst, the only guidance would come in the form of a multitude of existing Python package sources, available on GitHub and similar sites. Parroting them is certainly an option, although I believe it’s much more advantageous to acquire firm understanding of how those different cogs fit together. Without it, following the modern Python’s best development practices – which are all hugely beneficial – is largely impossible.

So, I want to fill this void by outlining the structure of a Python package, as completely as possible. You can follow it as a step-by-step guide when creating your next project. Or just skim through it to see what you’re missing, and whether it’d be worthwhile to address such gaps. Any additional element or file will usually provide some tangible benefit, but of course not every project requires all bells and whistles.

Without further ado, let’s see what’s necessary for a complete Python software bundle.
