Regular Expressions

Overview

Regular Expressions (Regex) define search patterns to extract or validate matching parts of texts.

When to Use This Skill

Use to extract emails, parse URLs, clean user inputs, or extract variables from raw HTML.

Quick Start (with runnable code examples)

import re

text = "Find me at [e-mail] and also [e-mail]"
# Extract all email patterns
emails = re.findall(r'[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}', text)
print("Emails found:", emails)

Advanced Usage

Design complex regex configurations with named lookarounds, non-capturing groups, and multi-line flag patterns.
