autopep8 0.8

A tool that automatically formats Python code to conform to the PEP 8 style guide

Latest Version: 1.3.3

About

autopep8 formats Python code based on the output of the pep8 utility.

Installation

from pip:

pip install --upgrade autopep8

from easy_install:

easy_install -ZU autopep8

Requirements

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

execute tool:

$ autopep8 TARGET.py

before:

import sys, os;
print(                'hello' );

def someone_likes_semicolons(                             foo  = None                          ,\
bar='bar'):
    """Hello; bye."""; 1; 2;3
    print( 'A'<>foo)            #<> is a deprecated form of !=
    return 0;
def func11():
    a=(   1,2, 3,"a"  );
    b  =[100,200,300  ,9876543210,'This is my very long string that goes on and on and on'  ]
    return (a, b)
def func2(): total =(324942324324+32434234234234 -23423234243/ 324342342.+324234223432423412191) /12345.
def func22(): return {True: True}.has_key({'foo': 2}.has_key('foo'));
class UselessClass(object):
    def __init__    ( self, bar ):
     if bar : bar+=1;  bar=bar* bar   ; return bar
     else: raise ValueError, 'I am an error'
    def my_method(self):
      print(self);

             324234223432423412191) / 12345.


def func22():
    return ('foo' in {'foo': 2}) in {True: True}


class UselessClass(object):
    def __init__(self, bar):
        if bar:
            bar += 1
            bar = bar * bar
            return bar

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)

Testing

Test cases are in test/test_autopep8.py. They can be run directly via python test/test_autopep8.py or via tox. The latter is useful for testing against multiple Python interpreters.

Broad spectrum testing is available via test/acid.py. This script runs autopep8 against Python code and checks for correctness and completeness of the code fix transformations. test/acid_pypi.py makes use of acid.py to test against the latest released packages on PyPi. In a similar fashion, test/acid_github.py tests against Python code in Github repositories.
