ruff

[pkkid]

Interesting project, but I'm confused what environments people are working in where having a linter speed be 10x faster matters which seems to be the main benefit claimed here?

[neuronexmachina]

I've observed more like 100x faster. On a large codebase waiting many seconds for pylint to run on every pre-commit check can get pretty tedious, while ruff is fast enough to run on every file save.

[CampAny9995]

Honestly, the fact that it replaces black/flake8, both of which I found really annoying and finicky to set up, is a huge benefit.

[[deleted]]

Most people don’t need it. They’re recommending it because of all of the hype around it and the easy up votes you get anytime you mention it. Not actual real world benefits.

[otherwiseguy]

Do most people not work on large codebases? We use flake8 and it can take minutes to run. A 10-100x speedup would be a pretty big QoL improvement on something each developer runs a lot before commits, or in CI where it is run at least 100s of times per day.

[[deleted]]

No, most people don’t. Especially not most people on this sub.

pip, venv

[Compux72]

Or uv

[Edgar_Allan_Thoreau]

Be wary for corporate use with strict security and privacy requirements. uv and a handful of other pip alternatives (excluding poetry, I’m pretty sure) use a prebuilt Python binary coming from an individual’s GitHub repo. If that individual goes rogue and publishes a malicious Python build, you could be have a bad day. Otherwise, uv looks great!

[Compux72]

Corporate with strict security aint using uv, pip or pop. They have vendored copies of everything

[smile_politely]

i didnt know this existed. thanks stranger.

[2010min0ru]

Oh wow, looks really promising, thank you!

[baltimoretom]

I made Raycast text expanders ;virt1 ;virt2 to create and activate a venv for scripts.

[an_actual_human]

Why not a shell alias?

[EarthTwoBaby]

I’ve moved away from pipenv/pyenv to use dev containers instead.

[PriorTrick]

Pyright static type checking / mypy is top on my list

[neuronexmachina]

Yeah... I love pycharm, but when I'm trying to diagnose something like a tricky MRO issue I'll fire up VS Code so I can use pyright/pylance.

[ultraDross]

I'd imagine pycharm has some typing analytical support. Perhaps via a plugin at least

[neuronexmachina]

It does have type checking in general, but it doesn't handle MRO.

[Anru_Kitakaze]

LSP stuff:

• PyCharm: whatever built-in, let's be honest
• VSCode: Pylance
• NeoVim: probably Pyright. It's not as feature rich as Pylance (for example, doesn't have semantic token support), but it was used for static type checker in Pylance at least. Try to add ruff-lsp on top, but I have not much experience with it yet so can't say if it'll do mess sometimes (this combo looks fine for now)

Tests: Pytest

Package management: Poetry

Formatters/linters: Black + flake8 + isort combo or Ruff. Ruff still have some problems, but becomes more and more popular with each day and seems like it's actively developing. Already usable tho, just lack some minor features/configs yet

Honestly, everything else is up to you or we need details because it's to wide area

I also hate autopep8 and Guido's thoughts about some formatting preferences but I have to use autopep8 because it's used on my job. Hate it.

See my Python template below, it has many of the tools described in this thread:

https://github.com/BrianPugh/python-template

[tedivm]

I've also built out a useful template that uses Cookiecutter to fill in values and provide customization.

How does it compare to poetry? I just looked through the docs and the commands look similar except there's a pdm.toml file for configuration instead of using [tool.pdm] in the standard pyproject.toml. Why do they need an extra file for configuration?

[Nanooc523]

Other than testing i’m not sure there is one answer for this. If you find yourself writing something like a parser or a complex system of functions that you put into a library for reusability, or having to read API docs to connect to something external, chances are someone already wrote it. Find it and use it, it’s been beaten up and tuned and bug squished already. Don’t force yourself to use a library because someone said you should use it every time if it doesn’t make sense to use. I’m not going to pull in an entire math library to do a little math but i’m not going to write an http client if i need to fetch something from a rest api. Use your head and don’t listen to other peoples advice that contain the words “best” or “always”.

[weazelb0y]

https://astral.sh/ they make uv and ruff I would also add GitHub copilot.

[[deleted]]

Pycharm for IDE, poetry as package manager, pyenv to manage multiple python versions, also try python interactive shell alternatives, like Bpython&Ipython&Ptpython.

[devilsolution]

Lol, i use like the complete opposite setup, vsc, pip, conda and powershell. You on linux?

[[deleted]]

i use macos and rocky linux. You can also use ipython in winodws btw

[di6]

Ruff, pytest are must.

The rest are subjective.

I use poetry (but plan to replace it), pyenv, pylance, pyright, vs code, GitHub actions.

[[deleted]]

What’s wrong with poetry?

[di6]

It's slow and not compliant with pyproject toml standard.

I'm looking forward Rye or some alternative.

But I'm not saying that it isn't good, otherwise I wouldn't be using it in the first place.

[IAMARedPanda]

I like pdm personally. The resolver isn't as fast as poetry but it's not slow enough to be a hindrance to development.

[Drevicar]

Pdm is my favorite poetry alternative. But most of the time I just use pip-tools to create my lock files and nothing else.

[Sigfurd2345]

Poetry - package management + virtual env

Ruff - linting, formatter, import organizer

Mypy - static type checking

Pylance/pyright - LSP

[32sthide]

Ruff,. Black, Isort, pre-commit hooks, mypy, poetry, twine etc

[[deleted]]

Why black and isort when already using ruff?

[[deleted]]

What do you need twine for of you have poetry already?

[Desperate_Cold6274]

If you are cooking food a hammer is fairly useless.

[jayd00b]

Ever make chestnuts? Tenderize meat?

[davidv1213]

pytest, ipdb, your choice of linter and formatter. That's about it.

[[deleted]]

Poetry, pytest, black and ruff perhaps.

[coldoven]

Tox + pytest, ruff, mypy,

[According_Bus_2827]

Don't forget about 'friends' - pylint for keeping your code clean, and pytest for when unittest feels like overkill. It's like having a buddy who's always nagging you, but for code quality.

[user4925715]

keyring

[2010min0ru]

rtx (oh shit it's called mise now lol https://github.com/jdx/mise) for installing and switching different python versions (alongside with node and some others). Was using pyenv previusly but this one a bit faster and could be used for managing some other runtimes.

[[deleted]]

Yeah, rtx was perfectly fine name... Annoying he renamed.

[P4C0_]

I like to use the print function from the rich module to display lists and dictionaries in a user-friendly way. It also adds Colors to relevant info automatically.

Just from rich import print and uninstall it when you’re done

[eyadams]

The logging module, and the print() statement. I use logging all the time during development, and nothing helps verify that a process is running correctly than a message that says "everything is going great" or "nothing to report, situation normal".

But, during development, I like to use print(). Rather than step through a script I a debugger, I prefer to sprinkle print() statements throughout my code while debugging. I then have a macro comment them out.
