I've noticed I have to drastically recalibrate when I'm looking at Python learning materials. I'm trying to find something good for onboarding people, but even the "advanced content" tends to be stuff like this. I'd consider advanced to be more along the lines of "your function returns a generator, here's how to write the type annotation," or "worked examples showing how to express computations using numpy so that your program runs 30x faster," or "here's how to write a context manager."
