In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
In this unit, you use the most common string methods in Python to manipulate strings, from simple transformations to more advanced search-and-replace operations.
