Subject: [PATCH v4 1/4] perf python: Prefer python3
Date: Tue, 14 Jun 2022 20:04:35 -0700	[thread overview]
Message-ID: <20220615030438.51477-2-irogers@google.com> (raw)
In-Reply-To: <20220615030438.51477-1-irogers@google.com>

The PYTHON_AUTO code orders the preference for the PYTHON command to
be python3, python and then python2. python3 makes a more logical
preference as python2 is no longer supported:
https://www.python.org/doc/sunset-python-2/

Reorder the priority of the PYTHON command to be python2, python and
then python3.
