Regular Expressions are a tool for searching and manipulating text. Most popular programming languages feature support for them and they are used widely across different disciplines. Regardless of whether you are a developer or engineer, being comfortable reading and writing regular expressions will benefit you.

They are a declarative way of specifying the desired structure of a piece of text. A regular expression can be used to extract information from a larger text, and to validate smaller pieces of text.

In this lab, you will use the Python programming language to learn the basics of how to use a regular expression and you'll learn about the different character classes available for matching different types of characters.
