Iterators, generators and decorators are language features of Python that allow to write elegant solutions for certain types of problems. This tutorial provides a hands-on introduction to the underlying concepts. Numerous examples show what you can do with them in your daily programming work.
You will learn how iterators, generators and decorators work and how to write better and more efficient programs with them. If you are new to these topics or tried but got confused about functions that return functions that return functions, this tutorial will help you to understand the how and the why.
This tutorial is a systematic introduction to the topics iterators, generators and decorators. It covers all relevant information with a focus on practical applications for common tasks.
