想了解python Autopep8实现按PEP8风格自动排版Python代码的相关内容吗,Data_IT_Farmer在本文为您仔细讲解python Autopep8自动排版的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:python,Autopep8自动排版,python,Autopep8,下面大家一起来学习吧。

Autopep8是一个将Python代码自动排版为PEP8风格的小工具。它使用pep8工具来决定代码中的哪部分需要被排版。Autopep8可以修复大部分pep8工具中报告的排版问题。

https://pypi.python.org/pypi/autopep8/

(1)安装步骤如下:

localhost:~ a6$ sudo pip install autopep8
Password:

Requirement already satisfied: autopep8 in /Library/Python/2.7/site-packages
Requirement already satisfied: pycodestyle>=2.3 in /Library/Python/2.7/site-packages (from autopep8)

(2)示例代码:

1)运行命令前代码的排版 (保存在test_autopep8.py)

import math, sys;
 
def example1():
  ####This is a long comment. This should be wrapped to fit within 72 characters.
  some_tuple=(  1,2, 3,'a' );
  some_variable={'long':'Long code lines should be wrapped within 79 characters.',
  'other':[math.pi, 100,200,300,9876543210,'This is a long string that goes on'],
  'more':{'inner':'This whole logical line should be wrapped.',some_tuple:[1,
  20,300,40000,500000000,60000000000000000]}}
  return (some_tuple, some_variable)
def example2(): return {'has_key() is deprecated':True}.has_key({'f':2}.has_key(''));
class Example3(  object ):
  def __init__  ( self, bar ):
   #Comments should have a space after the hash.
   if bar : bar+=1; bar=bar* bar  ; return bar
   else:
          some_string = """
            Indentation in multiline strings should not be touched.
Only actual code should be reindented.
"""
          return (sys.path, some_string)

2)运行命令

bogon:AB a6$ autopep8 --in-place --aggressive --aggressive test_autopep8.py

3)运行命令后代码的排版

import math
import sys 
def example1():
  # This is a long comment. This should be wrapped to fit within 72
  # characters.
  some_tuple = (1, 2, 3, 'a')
  some_variable = {
    'long': 'Long code lines should be wrapped within 79 characters.',
    'other': [
      math.pi,
      100,
      200,
      300,
      9876543210,
      'This is a long string that goes on'],
    'more': {
      'inner': 'This whole logical line should be wrapped.',
      some_tuple: [
        1,
        20,
        300,
        40000,
        500000000,
        60000000000000000]}}
  return (some_tuple, some_variable)
 
 
def example2(): return ('' in {'f': 2}) in {'has_key() is deprecated': True};
 
 
class Example3(object):
  def __init__(self, bar):
    # Comments should have a space after the hash.
    if bar:
      bar += 1
      bar = bar * bar
      return bar
    else:
      some_string = """
            Indentation in multiline strings should not be touched.
      Only actual code should be reindented.
      """
      return (sys.path, some_string)
