1.主机分组用字典做，客户机输入ip地址：主机名：账号：密码存入配置文件
2.接收正确的账号密码之后显示分组，分组之中可以查看主机名字
3.paramiko运行命令发送命令，用线程做出一个新的线程
 
运行：将屏幕的词进行运行，调用屏幕的字并且将其输入到文件处理的代码中
接收屏幕的字
选择相应的分组
产生线程并且连接
 
3.先创建一个实例
ssh = paramiko.SSHClient()
自动添加地址钥到known_host不出现yes选项
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
连接实例
ssh.connect(hostname=self.host,port=self.part,username=self.usename,password=self.password)
