What’s the best way to structure a Python project?

I’m starting a new Python project, and I’m not sure about the best way to structure it. I’ve seen some different approaches, but I’m wondering what’s considered a good project structure for larger projects.

Should I organize my code by functionality, with separate directories for each module, or by feature, with more granular submodules? How do I handle testing, documentation, and other resources in a way that keeps the project organized as it grows?

Any advice or resources on Python project structure would be greatly appreciated!
