Python 3: An interactive deep dive

Iterators are the “secret sauce” of Python 3. They’re everywhere, underlying everything, always just out of sight. [Comprehensions](https://www.educative.io/courses/python-3-an-interactive-deep-dive/diving-in-R8OkwwXzr4V/) are just a simple form of *iterators*. Generators are just a simple form of *iterators*. A function that `yields` values is a nice, compact way of building an iterator without building an iterator. Let me show you what I mean by that.

Remember [the Fibonacci generator](https://www.educative.io/courses/python-3-an-interactive-deep-dive/generators/)? Here it is as a built-from-scratch iterator:
