py3.5 telnet的实例（在远程机器上批量创建用户）

import sys
import telnetlib
import time

HOST = ["172.18.217.12","172.18.217.13"]#往后一直加即可

USER = "username"

PASSWORD = "password"

command1 = "net user test 1 /add" #添加用户

command2 = "net localgroup administrators test /add"  #给将用户添加到组

wait_time = 1

for host in HOST:

　　tn = telnetlib.Telnet(host,timeout = 10)
　　#tn.read_eager().decode('utf-8')

　　tn.read_until(b'login:')
　　tn.write(USER.encode('utf-8') + " ".encode('utf-8'))
　　time.sleep(wait_time)
　　#tn.read_very_eager().decode('utf-8')
　　
　　time.sleep(wait_time)
　　#tn.read_until(b' Administrator password: ')
　　tn.write(PASSWORD.encode('utf-8') + " ".encode('utf-8'))

　　time.sleep(wait_time)
　　tn.read_very_eager().decode('utf-8') #这句话的意思只是读取信息，但是撤掉就不能运行成功，不知原因，前面的如果不用read_until，全部用sleep的方法，则注掉的read_very_eager都要加上才能成功

　　tn.write(command1.encode('utf-8') + " ".encode('utf-8'))
　　time.sleep(wait_time)

　　tn.write(command2.encode('utf-8') + " ".encode('utf-8'))
　　time.sleep(wait_time)

　　a = tn.read_very_eager()
　　tn.close()
　　print(host + a.decode('gbk'))
　　print(' ')

解决了挨个建用户、加组的问题，所以一些用法并没有深究，这里的转码非常繁琐，而且， 没能执行成功 才可以
