filecmp模块单文件对比

filecmp是python的标准库自带的模块
[root@www difflib]# vim diff_one_file.py

!/usr/bin/env python

import filecmp

test1 =raw_input("please input you test1 An absolute path : ")
test2 =raw_input("please input you test2 An absolute path : ")

contrast = filecmp (test1,test2)
print contrast

创建一个文件的备份，然后对其备份进行修改。

[root@www difflib]# cp diff.html diff.htmlv2

[root@www difflib]# echo aaaa>>diff.htmlv2

测试：

[root@www difflib]# python diff_one_file.py
please input you test1 An absolute path : /root/python_auto/difflib/diff.html
please input you test2 An absolute path : /root/python_auto/difflib/diff.htmlv2
False
