Hi,
As I checked 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. For example,
re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an invalid escape
sequence, use raw strings for regular expression: re.compile(r"\d+\.\d+")).
In a future Python version, SyntaxError will eventually be raised, instead of
SyntaxWarning. (Contributed by Victor Stinner in gh-98401.)
I suppose I need to use raw string explicitly.
This is nasty change which affects many code out there. Sigh.
