Pre-release
This release is a pre-release and may not be stable for production use.
_sre.py is a reimplementation of CPython’s core regular expression engine, the _sre extension module. It’s written in pure Python to allow for easier experimentation and to benefit alternative Python implementations that can’t use C modules like the standard _sre. This version is compatible with _sre from CPython 2.3 and 2.4.
