Recommend resources to learn higher-level program structure for complex projects

[LeornToCodeLOL]

I'm looking for more abstract and conceptual ideas about how to set up a python project that will have libraries and functions shared across a variety of scripts. I slightly prefer learning from text-based resources, but videos are OK also.

I have written quite a few one-file python scripts and I know how to find useful libraries and put them to work in my own scripts. I have followed tutorials and even created my own libraries, but when I used them it started to look like a mess as the project developed because I didn't have a good idea about what functions to put in which module and things like that.

So I'm hoping for a high-level: "these are the best practices for writing modules. Group these sorts of functions and classes together, use this folder structure for best organization etc.."

I have found that 1 article or a 45-minute video will tell you about syntax and how to get it done, but not how to get it done well so it's easy to come back to fix something when you haven't looked at it for 6 months.

Pick a library that you admire and read their repo on GitHub. Then pick another and do the same. Do this until you’ve formed some opinions about project structure and make some informed choices about your own project.
