This book is one portion of Treading on Python Volume 2: Intermediate Python. That book covers this book and more. If you are interested only in iteration and generators, this book has you covered. Otherwise, check out Treading on Python Volume 2.

Iteration and Generators

Understanding iteration enables understanding generators and easily creating objects that can iterate. This guide will explain the theory behind iteration in Python and teach best practices for generator creation and use. Do not beware the yield; rather, embrace the power it provides.

The guide covers:

• Iteration protocol
• Iterators
• Iterables
• Class iteration
• The yield statement
• Generators
• Function generators
• Class generators
• Writing Python code like the masters

These constructs, while not necessary per se, allow you to be more succinct, reuse code, and think about code in a different way. You will learn:

• How the constructs work
• When to use them
• Real-life examples from the standard library
• How to understand others' code

This book covers many of these intermediate constructs that are available in Python. The book covers both Python 2 and 3. Topics include:

• Iteration
• Generators
• Using them with classes
• Real-world examples of their use
