At the point we're disagreeing about 'basic' vs. 'bit below intermediate'.. idk we at least have to agree how many levels the model has.

Fwiw I also thought it was pretty regular stuff, and then arcane library functions you've either needed or you haven't. Also, that's a generator, not a list comprehension.

One man's basic is another man's low intermediate.... but I agree that none of these seem overlooked to me,. They are pretty basic things once you get past the few chapters of your first python book.
