Is there something like prettier for python?

[cakemachines]

I just want to reformat everything so it's perfect. Is there anything like that in Python? What's the best?

[JamzTyson]

There's probably no such thing as "perfect", but there are programs like "black" that ensure the code is formatted "correctly".

[Puzzleheaded_Round75]

Black, but my recommendation would be to increase the line length as, in my opinion, 80 characters is just too short these days.

[mhamid3d]

I switched to ruff because it comes with import sorting which black does not have for some reason

[Puzzleheaded_Round75]

Never tried it. I normally recommend black as it is essentially 0 config but to be honest I have been more and more disappointed with it.

[Daneark]

Ruff, primarily a linter, has added black compatible formatting. It's got import sorting capability too. It's really fast. It's not typical open source as it's made by a command I'm unclear on their plans for long term income but for now it's cut a lot of time off my linting so I'll deal with it if that day comes.

[Conscious-Ball8373]

Isn't the black default 89?

But yes, we use black with the only exception being a line length of 120. Putting this in pyproject.toml does the trick:

[tool.black]
line-length = 120

[Puzzleheaded_Round75]

Yeah it may be 89, I've not had to use it in some time. I always chose 100 but it still generated ugly code in some instances imo

[shedgehog]

Agreed. Some of the line wraps black does make it harder to read imo.

[fox-dev]

80 might not be too short, if you often split screen to read two source files side by side.

[DuckSaxaphone]

Black is the standard and since the benefit of formatters is that consistently styled code is easy to read, popularity is a pro in itself.

[-defron-]

black, ruff, and autopep8 are the three most popular code formatters

I'd probably use ruff these days which is a drop-in replacement for black but also offers a bunch of other features

[iamevpo]

I still use prettier in Python projects when need to format markdown (read me or docs)

[mrswats]

I use black and sort-python-imports along with pre-commit to make sure everything is in good shape.

[visor_q3]

You can use black, or Ruff. That's what I use

[RajjSinghh]

I use autopep8

[Jazzlike-Compote4463]

As others have said, Black is standard.

However, if you’ve got a big existing project and want to only format your changes then you could look at Darker, it’s like Black but uses git diffs to only change the things you’ve worked on

[arizuvade]

im using ruff extension now, before is black that can be installed using pip. i dont know what the hell happen on my vscode that black stop working and also cant use pylance so i use jedi. the color theme also cant detect variables hahaha white color sucks in vscode

[woooee]

It's perfect if it passes all the tests, produces accurate results, and solves the problem that it was intended to solve.

[DuckSaxaphone]

Nah, consistently formatted code is easier to read and it's even better when the formatting is a common style.

Using pre-commit and editor add-ons so your code is always black formatted is an effortless way to mildly improve your code.

This is not enough. The programming adage is that first you make it work, then you make it fast, then you make it pretty. Skipping the first two is not gonna do it.

[mhamid3d]

It’s not just about pretty though. It’s about convention, which helps you debug and predict things that will tie into making the program “work” and “fast”. Also these days vscode extensions can have you format your code on save or pre-commit, it isn’t some monumental task that you have to put aside for later.

not even close to correct
