Pattern Matching in Strings

In Python, the re module provides powerful searching and pattern matching capabilities for finding information in strings. This module uses regular expressions to specify the patterns to be matched.

The following sections describe how to:

• Perform a simple match in a string;
• Use special characters to create patterns to be matched;
• Use a pattern to perform string substitution;
• Use flags to control pattern matching;
