Hi! This is Austin Cepalia with realpython.com. In this course, we’re going to learn all about Python’s built-in range() function.
00:10
I like to think of built-in functions, like range(), as some of the fundamental building blocks of Python programs. They make performing common tasks as simple as, well, calling a function! And because they are global functions, they are always available to us. By the end of this course, you’ll be comfortable using the range() function within your own Python programs.

We’ll start by learning about the basics of the range() function and how we can use it with definite iteration in the Python for loop.

We’ll learn about the three different implementations of the range() function, which will allow you to customize the output it generates. Finally, we’ll take a look at some advanced range() topics, and I’ll warn you about some of its limitations. Let’s get started.
