As a Python programmer, you’ll often find yourself needing to work with text data — whether it’s parsing log files, validating user input, or extracting information from web pages. Regular expressions (or “regex” for short) are a powerful tool that can help you tackle these text-related tasks with ease.
In this article, we’ll dive into the world of regular expressions and explore how you can use them to search, match, and manipulate text in your Python projects.
Understanding Regular Expressions
Regular expressions are a sequence of characters that define a search pattern. They allow you to perform complex text matching and manipulation operations that would be difficult or impossible to achieve with basic string methods.
Regular expressions are supported in many programming languages, including Python, and they follow a standardized syntax.
Searching and Matching with Regex in Python
In Python, you can use the re module to work with regular expressions. Let's start with a simple…
