Does Astronomer support Python 3.7?

As of today, Astronomer’s default docker images use Python 3.6.6. We’re looking to support Python 3.7 in upcoming releases, so stay peeled.

Python 3.7 isn’t (yet) supported by Airflow itself (1.10.3), but we do know that all of the core code supports it. You’re free to try it out, with the caveat that you might hit some bugs or errors with one-off hooks and operators that aren’t super common.
