✓ import regex

Ensure correct import path to avoid 'ModuleNotFoundError'

Basic usage of the regex module to find all words in a text.

import regex pattern = r'\b\w+\b' text = 'Hello, world!' matches = regex.findall(pattern, text) print(matches)

Debug

Known issues

breakingThe regex module is incompatible with PyPy due to differing string storage methods.

fix

Use CPython for compatibility.

affects: All

gotchaThe regex module releases the GIL during matching, which can lead to concurrency issues if the string is modified during matching.

fix

Ensure the string remains unchanged during matching when using concurrent=True.
