Python 3.12 question: SyntaxWarning: invalid escape sequence

[greenozon]

while trying to run the tool using Python 3.12
the script produces multiple warnings, eg:

C:\Dev\Debug\pycDcode.py:22: SyntaxWarning: invalid escape sequence '\ '
  BANNER = """
C:\Dev\Debug\pycDcode.py:42: SyntaxWarning: invalid escape sequence '\s'
  INSTRUCTION_REGEX = "\s\d+\s([A-Z_]+)"

...
```

Some hints to this mystery might be found over official python site: 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.)
