Evan Seabrook generates some docs:
As you can see above, we have docstrings defined for properties, methods and the classes themselves. Ultimately, these docstrings will be used by Sphinx to generate the documentation. If you’re using a different docstring format, you can use a Sphinx extension called Napoleon to use your existing docstrings. Once your project has a level of docstring usage that you’re happy with, we can move on to the next step of configuring Sphinx.
And that’s the downside to this: you get auto-generated documentation, which means it’s only as good as your developers’ ability to explain the code.
