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.
For example, a Boolean value like True or False is read-only, but you’ll find both mutable and immutable sequences in Python:A Python list represents a mutable sequence of arbitrary elements. A Python string is an immutable sequence of characters....
