upgrade to python 3.11+

upgrade python

LL runs on the deprecated heroku-18 stack, which is deprecated and can no longer be built for deployments. This is blocking all LL deployments.

We currently run python 2, which is not supported by any Heroku stacks beyond 18. To unblock deployments, we need to upgrade to python 3 (3.11+).

Could ChatGPT (or an AI-enabled IDE like Cursor) do this accurately, or at least help with it?

have you looked into the autoconversion tool provided by Python? I think its called 2to3 It should do some basic conversions like print" " becomes print(" ") and so on.

This a good idea--thank you Colin. I have seen a few of these tools over the years. Probably would be pretty effective for changing the LL code itself (although I have seen/heard that it is not always perfect and can introduce some painful bugs). I think an equally large issue is with dependencies and other infrastructure. There also needs to be a data migration from the old dynos to new dynos.
