Questions tagged [python-regex]

For questions about the 3rd-party regex module, which is a replacement for the standard RE module. DO NOT use this tag if you're not using or asking about this very module. For general Python regex questions please tag [python] [regex]. If you're using the built-in RE module use the dedicated [python-re] tag.

Created by Matthew Barnett, regex is a popular 3rd-party module for matching regular expressions in Python. It is backwards-compatible with the standard re module, but offers additional functionality.

The module can be installed with pip install regex, or found in standard repositories in many Linux distros, under the name python-regex (for Python 2) or python3-regex (for Python 3).
