I remember back in the day reading parts of the Python standard library. I don't know if that's generally good advice or still viable, but that's what I did, and I found it helpful. It was directly available, and usually connected to things I used with Python. One upside of this might also be that it's not as you said boilerplate, because it's very foundational and not heavily using other stuff. It also is well documented, so you'll find good explanations why things are the way they are.
