formatting - How do I autoformat some Python code to be correctly formatted? - Stack Overflow
I have some existing code which isn't formatted consistently -- sometimes two spaces are used for indent, sometimes four, and so on.

January 19, 2025What code formatter is the standard?
The formatter itself doesn't really matter. It's the style that it formats to that matters. PEP8 is the most popular style guide to format to by far when it comes to python. If you're not happy with autopep8, swap to a different formatter. I'm pretty sure a lottt of people use flake8. More on reddit.com

Use the Tab character for indentation. YAPF tries very hard to get the formatting correct. But for some code, it won't be as good as hand-formatting.

Also, as a safety measure which slows down processing, Black will check that the reformatted code still produces a valid AST that is effectively equivalent to the original (see the Pragmatism section for details). If you're feeling confident, use --fast. Black is a PEP 8 compliant opinionated formatter. Black reformats entire files in place. Style configuration options are deliberately limited and rarely added. It doesn't take previous formatting into account (see Pragmatism for exceptions).

autopep8
autopep8 would auto-format your python script. not only the code indentation, but also other coding spacing styles. It makes your python script to conform PEP8 Style Guide.
pip install autopep8
autopep8 your_script.py # dry-run, only print
autopep8 -i your_script.py # replace content
Update:
Many editors have pep8 plugins that automatically reformat your code right after you save the file. py-autopep8 in emacs
yapf
yapf is a new and better python code formatter. which tries to get the best formatting, not just to conform the guidelines. The usage is quite the same as autopep8.
pip install yapf
yapf your_script.py # dry-run, only print
yapf -i your_script.py # replace content
For more information, like formatting configurations, please read the README.rst on yapf github
Update 2:
Black
Black is much better than yapf. It's smarter and fits most complex formatting cases.

Edit: Nowadays, I would recommend autopep8, since it not only corrects indentation problems but also (at your discretion) makes code conform to many other PEP8 guidelines.
Use reindent.py. It should come with the standard distribution of Python, though on Ubuntu you need to install the python2.6-examples package.
You can also find it on the web.
This script attempts to convert any python script to conform with the 4-space standard.
