That cookbook article is a bad example, especially for normal users, since instead of explaining idiomatic cases of iteration, it explains several iteration constructs (where some are extremely complex) in one article: loop, iterate, for, mapcar, series, transducers

Built-in, of those above, are mapcar and loop.

Python iteration isn't so much about ranges, I thought. See: https://kinsta.com/blog/iterables-in-python/
