How do I automatically fix lint issues reported by pylint?

Question

Just like we have "eslint --fix" to automatically fix lint problems in Javascript code, do we have something for pylint too for Python code?

This is an old question, but voting to reopen as I don't really think it is seeking recommendations for books, tools, software libraries, etc; it's simply asking `pylint` has a way to automatically fix issues it finds- I was wondering the same thing and found this question. — Alexander Nied, Apr 01 '21 at 19:26
Pylint (still) don't have the feature to auto fix, but today there are other alternatives like Ruff (id:charliermarsh.ruff) that can fix things. For an existing codebase with many lint errors, running for example Ruff can give you a running start in fixing all these errors. After that you can continue using Ruff, or switch to Pylint depending on your preferences. — Andreas Lundgren, Jul 05 '23 at 06:09

Some of the formatting-errors reported by pylint can be fixed with autopep8, black, or the built-in formatting supported by PyCharm and other IDEs.

Here is an example command using `autopep8`: `autopep8 --in-place --aggressive --aggressive *.py` – Tyler Chong Jan 03 '22 at 02:17
@TylerChong That example does not work in version 1.6.0 as it does not recognize *.py. Could you please provide an updated command that checks all files? – Dan Jul 30 '22 at 02:10

autopep8 fixes only a small number of the errors reported by pylint. My code had a 1.95/10 rating after autopep8, with previous run at 0.39/10. – Lucas Gonze Sep 01 '22 at 00:15
AutoPep8 works well enough for me ( I am able to use the custom rules from the internal Google pylintrc file) from this link: https://google.github.io/styleguide/pyguide.html – Anshuman Kumar Feb 11 '23 at 11:57

You also have black now. Both black and autopep8 can be integrated into most good editors.

Unfortunately `black` fixes only a small number of the errors reported by `pylint`, even when combined with `autopep8`. – Serrano Sep 07 '22 at 06:23
Isn't Black highly opinionated? It would not work with a custom Pylintrc script, right? – Anshuman Kumar Feb 11 '23 at 09:04

There is also autoflake which removes unused variables and imports.

Note that it only removes unused imports from the standard library by default, to ensure that there are no side-effects.

Example usage:

autoflake -r --in-place --remove-unused-variables src/
