I'll give a plug for 'Cosmic Python'[0], it goes into detail of structuring larger python applications using hexagonal-ish architecture. I wouldn't recommend this approach for smaller services.
I'd personally like to see more python books like Cosmic Python, that delve into how to build enterprise applications with the language. Feels like an unserved market compared to all the python related data science books that are really popular.
That said, at some point it starts to make sense to read open source repositories to pick up useful patterns.
