This was raised as part of discussing #8665: We support Python 3.5 through 3.9, but our Dockerfile default is Python 3.7.

Is there any particular reason for this, or should we go full steam ahead with the latest supported Python version in our Dockerfiles since we effectively control that environment?

it's a bit balanced between "which python versions are likely to be cached locally as images?" (deduplication on admin side) and "which versions do we trust the most/do we think have the most benefit with performance and the like?" (as effectively support and benefit of 3.5 through 3.9 is indistinguishable)

Imo: Latest python release - 1 minor version

were only talking a few meg on that python layer tbh, debian-slim takes up the vast chunk of it (And didnt provide the precompiled wheels we were hoping for). Whatever version is stable, might as well (id argue keeping it at the same version as the latest ubuntu LTS or something as well, so at least any bugs would be global is how id see it - which in this case is 3.8)

the same version as the latest ubuntu LTS or something

Ah, but which something 😉

Distro Python
RHEL 8 3.6
Debian 10 3.7
Ubuntu 20.04 3.8

If the latest version of Python is x.y, I'm inclined to go with x.(y-1). This gives us a very recent version of Python, but also one which has been around long enough for the broader ecosystem to adapt to any changes it introduces.

Im in favour of 3.8 since that matches 20.04 and matches the y-1 rule. Seems a win all round to me :). Alas, ill leave that to the grown ups!

This bumps us closer to current Python without going all the way to 3.9.

Fixes matrix-org#8674
