Question

Is there any library that takes in your python file as input and does tidy-up (modifies it based on the PEP 8 conventions).
To understand what I am talking about, a JavaScript analogy is as follows:

1. Go to this link
2. Press the button TidyUp

Any online editor or library or script would be appreciated.

Answer 1

You can take a look to PythonTidy which is officially working till python2.5 (and seems to be supported in python2.6) :

Cleans up, regularizes, and reformats the text of Python scripts.

This script reads Python code from standard input and writes a revised
version to standard output.
