You're singling out the async example while I was referring to the 3rd party libraries you listed. Of course you're always understanding the language through some use case (web programming, data science, ML, whatever) and that will require to learn the relevant libraries but adding another use case or a different solution for the same use case doesn't necessarily teach you more about the language.

My point is that OP can stick to the use case they're already working on and still get better at Python (that's what the resources I pointed to help with).
