with package pinning
and package management for Python projects in the
Wikimedia ecosystem?
Yes! That would be awesome. I have spent a lot of time floundering in
this area trying to make decisions; it'd be nice if we had a good guideline
established.

Awesome! Did you consider conda envs? FWIW, we rely on conda envs
<https://gitlab.wikimedia.org/repos/data-engineering/workflow_utils#building-project-conda-distribution-environments>
in the Data Engineering world to work around the lack of ability to
securely run docker images in production. We didn't try pyenv, mainly
because conda gets us more than just python :)
tool worth looking into
Poetry was nice, but I found that it wasn't as comprehensive (yet?) as ye
old setuptools based stuff. I can't quite recall what, but I think it was
around support for datafiles and scripts? But, this was 1.5 years ago so
maybe things are better now.
Thank you!

tutorial that will be published to the wikis when ready. Maybe that could
be expanded upon? In my experience though, it can be hard to get people to
agree on following a standard, especially when there are so many different
options and many folks already have their favorite tools and workflows. But
it would be nice to have a set of recommendations to reduce the cognitive
load.
