An iterable object is any object that can be stepped through. Iterable objects include lists, sets, tuples, strings, dictionaries, ranges, and files. An iterator is an object that implements a method for stepping through the elements of an iterable.
For example, you can get a list iterator by saying it = iter([2, 3, 5]). You can step through the elements of this list by repeatedly calling next(it) ...
