Course overview

In this course, you’ll learn how to make high-quality functions by giving them docstrings and restricting them to doing only one thing. You’ll also learn how to make a function using the DRY principle (“Don’t Repeat Yourself”), which helps you recognize when you need to pull part of your code into a reusable function.

You’ll learn how Python passes arguments to functions, as well as the difference between mutable and immutable variables. Finally, you’ll explore how to write your own context managers using decorators.

By the end of this course, you’ll know how decorators work, why they work, and how to use them.

Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser.
