I'm working on an "Essential Tools for Managing Python Development Environments <https://docs.google.com/document/d/1pl6QCDWGebGjRrHixgQNES8qRf-8PCzwLSsFj7jI1HY/edit#heading=h.i5ou2ywgmb09>" tutorial that will be published to the wikis when ready.

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. -- Slavina Stefanova (she/her) Software Engineer - Technical Engagement Wikimedia Foundation On Fri, May 5, 2023 at 5:18 PM Kosta Harlan &lt;kharlan(a)wikimedia.org&gt; wrote:

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. Environments <https://docs.google.com/document/d/1pl6QCDWGebGjRrHixgQNES8qRf-8PCzwLSsFj7jI1HY/edit#heading=h.i5ou2ywgmb09>" tutorial 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!

I tried conda a few years ago, but for my own use cases, I found it mostly got in my way. I know it's big with data and science folks though, so I will add it to an "other tools to be aware of" section. But now I'm curious about how conda enables running docker safely in production. :) For anyone interested in the (bewildering complexity of the current) Python packaging ecosystem, I can recommend this blog post by PyPA member and PSF fellow Pradyum Gedam: https://pradyunsg.me/blog/2023/01/21/thoughts-on-python-packaging/ <https://pradyunsg.me/blog/2023/01/21/thoughts-on-python-packaging/> -- Slavina Stefanova (she/her) Software Engineer - Technical Engagement Wikimedia Foundation On Mon, May 8, 2023 at 3:03 PM Andrew Otto &lt;otto(a)wikimedia.org&gt; wrote:
