#!/usr/bin/env python

#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
