这里有新鲜出炉的Python3 官方中文指南，程序狗速度看过来！
Python编程语言
Python 是一种面向对象、解释型计算机程序设计语言，由Guido van Rossum于1989年底发明，第一个公开发行版发行于1991年。Python语法简洁而清晰，具有丰富和强大的类库。它常被昵称为胶水语言，它能够把用其他语言制作的各种模块（尤其是C/C++）很轻松地联结在一起。
本文是一个python实现的可以批量修改linux服务器密码并生成execl的示例代码,需要的朋友可以参考下
批量修改linux服务器密码，同时生成execl表格
#!/usr/bin/env python
#coding:utf8
#随机生成自定义长度密码
