Answer 1

As of 2019-12-17, version 274.0.0 officially supports Python 3. Release notes:

Cloud SDK now has GA support for Python 3. Please run gcloud topic startup for:

• Information on configuring the Python interpreter used by the Cloud SDK.
• List of tools in the Cloud SDK that still require a Python 2.7 interpreter.
• List of known issues with Python 3 support.

(That command shows that dev_appserver and endpointscfg are the exceptions.)

According to the search order, gcloud will still use Python 2 if it finds it. You can be explicit by setting CLOUDSDK_PYTHON=python3 (or similar) as an environment variable.
