Quick Answer
Iterable: object you can loop over - has __iter__() returning an iterator. Lists, tuples, strings, dicts are iterables. Iterator: object with __next__() - stateful, remembers position, consumed once. Iterables can create multiple iterators. iter(mylist) creates an iterator from a list. Generators are iterators. For-loop calls iter() then repeatedly calls next() until StopIteration.
