使用python怎么批量修改服务器的密码-创新互联
本篇文章给大家分享的是有关使用python怎么批量修改服务器的密码，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
1、在现有的excel密码表格，在最后一个字段后面生成新的密码，另存为一个新的excel密码文件
2、根据新的excel密码文件，更新服务器密码，将更新后的结果保存到另外一个excel文件。
a、原始excel文件字段格式，最后一个字段为原始密码
IP USER PORT pwd
b、生成新的密码文件字段格式，最后一个字段为更新密码
IP USER PORT pwd pwd20180929
c、生成新的密码文件字段格式，最后一个字段为更新是否成功的标识
IP PORT USERNAME OLDPASS NEWPASS FLAG
按照面向对象编程的思想，可以设计2个类，excelhandler和ChangePassword
excelhandler主要负责excel文件的读取，写入，增加一个生成密码文件
ChangePassword主要利用paramiko登陆服务器进行密码更新
excelhandler类
