5. About autopep8 simple command-line tool automatic formatting for Python Code require v0.9.4 (2013.09.08) pep8 $ pip install autopep8
6. For Example invalid PEP 8 code import sys, os n = True if n != None: print("none") def f(x): return 2 * x
7. Output Auto-Formatting Code $ autopep8 invalid.py import sys import os n = True if n != None: print("none") def f(x): return 2 * x
8. Aggressive $ autopep8 -a invalid.py import sys import os n = True if n is not None: print("none") def f(x): return 2 * x
9. Print Diff $ autopep8 -d invalid.py --- original/invalid.py +++ fixed/invalid.py @@ -1,7 +1,10 @@ -import sys, os +import sys +import os n = True if n != None: print("none") -def f(x): return 2 * x + +def f(x): + return 2 * x
