Regular Expressions and Building Regexes in Python

In this course, you’ll explore regular expressions, also known as regexes, in Python. A regex is a special sequence of characters that defines a pattern for complex string-matching functionality.

String matching like this is a common task in programming, and you can get a lot done with string operators and built-in methods. At times, though, you may need more sophisticated pattern-matching capabilities.

In this course, you’ll learn:

• How to access the re module, which implements regex matching in Python
• How to use re.search() to match a pattern against a string
• How to create complex matching pattern with regex metacharacters
• Explore more functions, beyond re.search(), that the re module provides
• Learn when and how to precompile a regex in Python into a regular expression object
• Discover useful things that you can do with the match object returned by the functions in the re module
