Python实现字典去除重复的方法示例_Python

本文实例讲述了Python实现字典去除重复的方法。分享给大家供大家参考，具体如下：

									#!/usr/bin/env python

									# encoding: utf-8

									#字典去重小代码

									import sys

									import os

									import platform

									try:

									  pass

									except:

									  print '''you have something wrong this is a simple jiaoben '''

									  sys.exit()

									why = 'why.txt'

									for i in xrange(len(sys.argv)):

									  if(i>=1):

									    other = sys.argv[i]

									    if os.path.exists(other):

									      pass

									    else:

									      print other + ' file not find'

									      sys.exit()

									    if 'Windows' in platform.system():

									      os.system("type "+other+" >> "+why)

									    else:

									      os.system("cat "+other+" >> "+why)

									yuan = open('why.txt','r')

									dirc = open('whynot.txt','w')

									for line in set(yuan.readlines()):

									  if line == '' or line == '\r\n':

									    pass

									  else:

									    dirc.writelines(line)

很简单的思路把文件放入到why.txt中然后再去重得到whynot.txt
Usage: quchong.py 1.txt 2.txt 3.txt 等等

希望本文所述对大家Python程序设计有所帮助。
