An honorable mention of norvig's classic essays, which got me into python while I was in college, over 12y ago: https://norvig.com/spell-correct.html.
Aside from reading code, _writing_ something that you know it exist (e.g glom) and then comparing it to how others have done it is also a great learning experience.
