(In reply to Mike Hommey [:glandium] from comment #28) > The Linux builds on automation are using python 3.5. I think it's fair to maybe require a newer version for tests, but we should at least keep 3.5 for the build system. Sounds good. The downside to using a different version for non-build things is that people might get used to using e.g f-strings and accidentally add one to a shared library that the build uses (e.g mozbase). Not a huge deal as it will get backed out, but could still be annoying. Whether or not we standardize on a single Python version, we'll need to make sure the unittests for various modules are all running with the minimum.

Ubuntu 14.04 LTS (eol April 2022), seems to come with 3.4. By that logic shouldn't 3.4 be the minimum? Also 16.04 eol is 2024. Will the build system be stuck on 3.5 for another 5 years? If that's the case, then yeah.. maybe it would be better to use a more modern version for non-build things in the meantime.
