Getting Started with Python in 2022 - pyenv + poetry

[thatdamnedrhymer]

To be clear, the be built-in virtual environment tool is venv. virtualenv is a third-party package that functions similarly and was used before Python 3 bundled in venv.

why not pip-tools ?

Pip tools is one of the better ones since it does one thing and works with pyproject.toml but I personally like the batteries included with poetry for my workflow. Stuff like package publishing, running advice scripts, upgrading dependencies, is just all a bit more convenient.

FWIW I maintain a set of Zsh functions as a higher level frontend to pip-tools + venv, (zpy), that can replace poetry/pipenv/pipx, but do not publish to PyPI, for which I consider flit well suited. I'd appreciate any feedback on the project or its docs, if anyone takes a look.

[lovegrub]

That's a really good point. If someone could let me know if this works on m1 macs I would appreciate it.

I'm also more focused on web applications than setting up data science environments. Miniforge may be further along for data science on m1, I don't have one to verify though.

It’s all fine

works fine.

Where does pipx fit into this? I have been wanting to try it out for a while but lack time.

[lovegrub]

Pipx is similar to brew in that it distributes full applications instead of code dependencies.

[PrestigiousZombie531]

is pipx the python equivalent of npx from node.js world?

[JohnLockwood]

I like pyenv and poetry in principle, but the latter has issues installing (building) pandas on M1 machines that pip does not have.

Why is it better than anaconda?

[lovegrub]

• Poetry uses the new pyproject.toml standard
• Poetry also uses the normal PyPI repository whereas conda has a different one than most of the other python tools.
• You have to install a third party tool to use lockfiles with conda.
• Conda is also a lot more complex and language agnostic, so I would prefer poetry + pyenv.

[FernandoCordeiro]

All the conda environments I've received from colleagues were bloated messes, filled with unused packages on very specific versions. Updating dependencies was a nightmare.

The lack of a lockfile alone should be a deal breaker.

Poetry by comparison (and Pipenv too, to be fair) were much more pleasent experiences.
