Introduction to Iterators

Explore the concept of iterators and generators in Python, understand how iterator objects are created with __iter__ and __next__ methods, and learn to use them for efficient iteration over data structures without manually handling exceptions or calls.

We'll cover the following...

Iterators
How list is not an iterator?
Trying loops with iterator

We have probably been using iterators and generators since we started programming in Python but we may not have realized it. In this chapter, we will learn what an iterator and a generator are. We will also be learning how they are created so we can create our own when we need to.

Iterators

An iterator is an object that will allow us to iterate over a container. The iterator in Python is implemented via two distinct methods: _iter_ and _next_. The _iter_ method is required for our container to provide ...
