python 作业
1.增删改查haproxy.conf配置文件
1.查询输入：www.oldboy1.com
2.删除输入：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}
3.增加输入：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}
4.修改输入：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}
修改之后：{'backend': 'www.oldboy2.org','record':{'server': ["1.1.1.1","2.2.2.2"],'weight': 20,'maxconn': 30}}

2.用户认证
用户输入账号密码三次错误，程序终止
如果三次都是同一用户错误，锁定用户

1.定义一个字典，用户每次错误向字典增加记录{name count},当用户输入错误3次退出时， 判断字典的值是否大于3，大于3写到锁定文件 |
