Documenting Python Code: A Complete Guide

By · Published by Everything Blog

In short

Proper software stewardship relies on distinguishing between comments and documentation, as each serves a fundamentally different audience. Comments use brief statements, often prefaced with a pound sign, to clarify design decisions for developers maintaining the codebase. Documentation instead guides users through the overarching functionality and practical implementation of the software. To establish these best practices, developers can utilize docstrings across scripts, modules, packages, classes, and functions alongside interactive learning tools.
