我在 linux 机器上运行 python (ver. 2.6.2) 并且需要能够远程登录到一长串设备 (大约 300) 发送命令“sho ser”并将该命令的结果输出返回到文件并且列表中的每个顺序设备然后将其输出添加到新行。所有设备都列在文件的不同行中

我发现了一些让我从另一篇文章开始的代码，但我不知道从哪里开始。我可以打开我称为“主机列表”的列表，但我不确定如何告诉 python 远程登录到一个设备，运行命令，退出，然后转到下一个。任何帮助将不胜感激

import getpass
import sys
import telnetlib

f = open('hostlist', 'r')

HOST = "%s" % f
user = raw_input("Enter your login name: ")
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)

tn.read_until("login: ")
tn.write(user + "\n")
if password:
    tn.read_until("Password: ")
    tn.write(password + "\n")

tn.write("show ver\n")
tn.write("exit\n")

print tn.read_all()

收到此错误

Enter your login name: K3grb6hj9ld93a2
