Hypermodern Python

I probably haven't bought into all of poetry yet but for deployment, I have been using "poetry export" to get the pinned requirements.txt, commit it to the repo and install to a virtualenv. A bit of work to keep it in sync with the poetry dependency file but that's ok.

For PATH with cron or others, I use the full path to the virtualenv such as /path/to/project/.venv/bin/python. The path can be extracted by "which" or "Get-Command" when the venv is active.

Using a python version different from the system python version is probably the messiest part but well, targeting 3.6 is alright.

I do agree it could be better and it's not quite as streamlined as other ecosystems.

Honestly, pip freeze includes the whole content of a venv site-packages, and the exact versions. For most projects, that's equivalent to all the dependancies recursively pins with peotry, although you don't have the clean pyproject-dev-prod/lock file separation.

So a huge number of cases can be handled with just that. It will be "reproducible" enought for a lot of people.

That's why I use "poetry export -f requirements.txt > requirements.txt" instead of pip freeze. It only exports prod requirements from the poettry lock file.

Nice trick, and very useful to make sure people never have to know about poetry if your team can't deal with it.
