lukel97 · web-flow · commit 5148f0beb788 · 2024-02-20T08:18:43.000-08:00
As of Python 3.12 there's now a syntax warning for invalid escape sequences: ./utils/compare.py:195: SyntaxWarning: invalid escape sequence '\g' This fixes it by using a raw string literal, as recommended here: https://docs.python.org/3/library/re.html
