Slightly OT: this seems like a good way to learn to program. My wife has been trying to learn to program with python but all the tutorials even programming 101 tutorials these days actually seem more advanced than I would expect. For example they assume someone gets what a string is and how it works with surprisingly very little explanation, then overload the student by comparing the difference between string objects in Python 2 vs Python 3 and Unicode va non-Unicode! Woah object, Unicode, what? Are there any good resources for progressively learning Python by doing something like AOC but starting from nothing and as a tutorial and explaining the basics of what a string is etc as it goes?
