Ruff is a particularly quick Python linter and formatter written in Rust that goals to interchange and enhance upon present instruments like Flake8, Black, and isort. It offers 10-100x sooner efficiency whereas sustaining parity by over 700 built-in guidelines and reimplementation of widespread plugins.
Stats from Ruff | Linting the CPython codebase from scratch
Ruff helps fashionable Python with 3.12 compatibility and `pyproject.toml`. It additionally affords computerized repair help, caching, and editor integrations. Ruff is monorepo-friendly and utilized in main open-source initiatives like Pandas, FastAPI, and extra. By combining velocity, performance, and value, Ruff integrates linting, formatting, and computerized fixing in a unified instrument that’s orders of magnitude sooner than present choices.
We will simply set up `ruff` through the use of PIP.
To check how simple and quick it’s to run Ruff, we will use the DagHub repository kingabzpro/Yoga-Pose-Classification. You may clone it or use your personal venture to format.
Mission Construction
First, we are going to run a linter over our venture. It’s also possible to run linter on a single file by changing “.” with file location.
Ruff has recognized 9 errors and 1 fixable error. To repair the error, we are going to use the –fix flag.
As you possibly can see, it has fastened the 1 fixable error.
To format the venture, we are going to use the `ruff format` command.
$ ruff format .
>>> 3 information reformatted
The Ruff linter and formatter have made quite a few modifications to the code. However, why will we require these instruments? The reply is easy – they’re useful in imposing coding requirements and conventions. In consequence, each you and your workforce can think about the numerous points of your code. Furthermore, they assist improve the standard, maintainability, and safety of our code.

To make use of Ruff for Jupyter Notebooks within the venture, you must create `ruff.toml` file and add the next code:
extend-include = ["*.ipynb"]
It’s also possible to do the identical with the `pyproject.toml` file.
After that re-run the instructions to see it making modifications to Jupyter pocket book information.
2 information had been reformatted and we’ve 2 Pocket book information.
$ ruff format .
>>> 2 information reformatted, 3 information left unchanged
Now we have additionally fastened the problems in these information by working the `test` command once more.
$ ruff test --fix .
>>> Discovered 51 errors (6 fastened, 45 remaining).
The ultimate result’s wonderful. It has made the entire essential modifications with out breaking the code.

line-length = 80
[lint]
extend-select = [
"UP", # pyupgrade
"D", # pydocstyle
]
[lint.pydocstyle]
conference = "google"
