Python is one of my primary languages (the other one being Rust). But it honestly isn’t the easiest language to teach - I’m saying this from experience. There are so many concepts at play - name binding, iterators, generators, exception chains, context managers, decorators, … . I could go on and on. Teaching becomes hard because any basic question could become a journey into the rabbit hole of python semantics.

Python is, however, a good first language for self learners. (Note: teaching vs learning). Python behaves intuitively. It’s designed in such a way that if you guess something about the language, you’ll probably be right.
