I have a large body of python code that needs to have a pep8-compliant style/format imposed on it. There are variants of pep8 that various rules (like this one by a coworker ), but the hardest thing is to deal with splitting too long lines and formatting the modified code. I've looked up the questions on this: python-formatter-tool python-source-formatter-pretty-printer They are from 2009 and 2010. I am hoping that better tools have been developed since then. I know about PythonTidy which is pretty good but makes lots of code worse, IMHO. Pylint detects formatting errors but does not correct them. Web services are not really relevant to my requirements because I want a tool that can be part of a build. Does anyone have a recommendation that has not already been covered? Thanks.

black is another contender. It's selling point is that is is barely configurable, so your team wastes less time quibbling about details.

There's an online demo here: black.now.sh

Side-note: black, yapf, and autopep8 have python language server plugins, so they integrate nicely with text editors including atom and vscode.

Google's yapf works very well.

There's an online demo here: yapf.now.sh

You can integrate it into your workflow and run it when you save files in your editor or as a git precommit hook or something like that.

PyCharm has this functionality built in and now has a free, open source community edition. Open your file up in it and hit CtrlAltL.

Unifortunately, it will not also automatically refactor function names and variable names to PEP8 convention... those will have to be done one by one with PyCharm's rename functionality.
