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

Project Description

Build status

About

autopep8 automatically formats Python code to conform to the PEP 8 style guide. It uses the pep8 utility to determine what parts of the code needs to be formatted. autopep8 is capable of fixing most of the formatting issues that can be reported by pep8.

Installation

from pip:

pip install --upgrade autopep8

from easy_install:

easy_install -ZU autopep8

Requirements

autopep8 requires pep8 (>= 1.3.2). 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);

after:

import sys
import 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 ('foo' in {'foo': 2}) in {True: True}


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)

options:

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; multiple -v result in more
                        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       fix only these 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.
