>From c7d6289573379be760ca9d691d62e0f87ba0ee8a Mon Sep 17 00:00:00 2001
From: "Sv. Lockal" <lockalsash at gmail.com>
Date: Wed, 27 Mar 2024 14:03:34 +0000
Subject: [PATCH 1/2] Fix SyntaxWarning messages from python 3.12

This fixes "SyntaxWarning: invalid escape sequence" and "SyntaxWarning: "is" with 'int' literal",
except for polly and summarizeStats.py, which won't run on Python 3.

The fix is done in every file, because otherwise with OS-wide Python 3.12 these SyntaxWarnings appear here and there.

There are no warnings anymore, which can be checked with `python -m compileall -x "polly|summarizeStats.py" -d . -f -q .`
