About autopep8 simple command-line tool automatic formatting for Python Code require v0.9.4 (2013.09.08) pep8 $ pip install autopep8 

For Example invalid PEP 8 code import sys, os n = True if n != None: print("none") def f(x): return 2 * x

Aggressive $ autopep8 -a invalid.py import sys import os n = True if n is not None: print("none") def f(x): return 2 * x
