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 set of labs, 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.

Learning Objectives

Upon completion of these beginner-level labs, you will be able to:

• Implement a Regular Expression using Python
• Use different features of Regular Expressions to match subsets of a piece of text
• Recognize when Regular Expressions are a good solution and when something else should be preferred

Intended Audience

• Developers
• Engineers

Prerequisites

Familiarity with the Python programming language will be beneficial but is not required.
