Regular expressions are essential for pattern matching in text. This post
covers re.search, re.match, re.findall, grouping, and common patterns.

Quick example:

import re
email_re = re.compile(r"([\w.-]+)@([\w.-]+)\.(\w+)")
match = email_re.search('contact me at [e-mail]')
if match:
    print(match.groups())

Tips: build patterns incrementally, use raw strings, and test with online tools.
