Bug:
Due to the changes in python 3.12, incorrect escape sequence generates a syntax warnings.
https://docs.python.org/3/whatsnew/3.12.html
A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning.
There are such escape sequences in code comments.
Expected behavior:
No syntax warnings when using python 3.12
