Popular examples of iterators
In this video, I show how we were using iterators already long before we formally introduced them in this course. For example, the range() built-in creates objects that behave like iterators (although they are actually not iterators). Other examples of iterators are the objects returned by the reversed(), zip(), and enumerate() built-ins. The commonality among them is that all of them model "rules in memory" that know how to generate a "next" element without generating it yet.
