autopep8 formats Python code based on the output of the pep8 utility.
from pip:
pip install --upgrade autopep8
from easy_install:
easy_install -ZU autopep8
autopep8 requires pep8 (>= 1.3). Older versions of pep8 will also work, but autopep8 will run pep8 in a subprocess in that case (for compatibility purposes).

Usage: autopep8 [options] [filename [filename ...]]
A tool that automatically formats Python code to conform to the PEP 8 style
guide.
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-v, --verbose print verbose messages
-d, --diff print the diff for the fixed source
-i, --in-place make changes to files in place
-r, --recursive run recursively; must be used with --in-place or
--diff
-p PEP8_PASSES, --pep8-passes=PEP8_PASSES
maximum number of additional pep8 passes (default:
100)
--ignore=IGNORE do not fix these errors/warnings (e.g. E4,W)
--select=SELECT select errors/warnings (e.g. E4,W)
