python自动化运维 第2章 业务服务监控详解 2.1.1

环境配置

1、RHEL6.4CLIENT 192.168.153.132

1、两个字符串的差异对比例子：

#!/usr/bin/python

import difflib #插入difflib模块

text1 = """text1: #定义字符串text1

This module provides classes and functionsfor comparing sequences.

including HTML and context and unifieddiffs.

#使用diffs模块可以对类与函数之间进行比较包括HTML上下文。

difflib document v7.4

add string #添加字符串

"""

text1_lines = text1.splitlines() #进行分隔，以便进行比较

text2 = """text2: #定义字符串2

This module provides classes and functionsfor Comparing sequences.

including HTML and context and unifieddiffs.

difflib document v7.5"""

text2_lines = text2.splitlines()

d = difflib.Differ() #创建Differ()对象

diff =d.compare(text1_lines,text2_lines) #采用compare方法对字符串进行比较

print '\n'.join(list(diff))

(注意：如果要拷贝这个脚本的话，记得把注释全部清掉，不然执行不了，我这里添加注释方便理解)

2、将第1个字符串例子修改为

#!/usr/bin/python

import difflib

text1 = """text1:

This module provides classes and functionsfor comparing sequences.

including HTML and context and unifieddiffs.

difflib document v7.4

add string

"""

text1_lines = text1.splitlines()

text2 = """text2:

This module provides classes and functionsfor Comparing sequences.

including HTML and context and unifieddiffs.

difflib document v7.5"""

text2_lines = text2.splitlines()

d = difflib.HtmlDiff()

diff =d.make_file(text1_lines,text2_lines)

print '\n'.join(list(diff))
