Python, I believe, has some kind of `Iterable` interface, which a generator satisfies and which specifies the method to call to get the next value. In Racket maybe one would have to do with a convention of how to get a next value from a lazy list.
Python's concept of iterables is very similar to Racket's streams (https://docs.racket-lang.org/reference/streams.html) and sequences (https://docs.racket-lang.org/reference/sequences.html). And Python generators are very similar to Racket generators (https://docs.racket-lang.org/reference/Generators.html). The main difference, as has been pointed out before, is that Python generators are more common as an idiom for solving problems that in Racket would typically be approached differently.
