Subject: [PATCH v2 4/7] scripts: fix Python string escapes
Date: Tue, 12 Sep 2023 16:07:58 +1000	[thread overview]
Message-ID: <20230912060801.95533-5-bgray@linux.ibm.com> (raw)
In-Reply-To: <20230912060801.95533-1-bgray@linux.ibm.com>

Python 3.6 introduced a DeprecationWarning for invalid escape sequences.
This is upgraded to a SyntaxWarning in Python 3.12, and will eventually
be a syntax error.

Fix these now to get ahead of it before it's an error.
