python 3 使用列表项发出 Cisco IOS 命令

Question

Python 在第一个命令上执行以收集特定接口并添加到列表中。第二个命令获取列表项（接口）以运行命令。不确定如何让第二个命令一个一个地抓取列表项。我在想我需要利用 for 循环来完成这个吗？任何帮助将不胜感激。请参阅下面的 Python 代码和从 Jumpstation 执行时产生的输出。谢谢！

Python Code:
#!/usr/bin/env python3.4
from os.path import expanduser
import sys
import subprocess

#define Function
# while loop to provide user input
def get_user_input(prompt):
    while True:
        try:
            value = input(prompt)
            if not value:
                raise ValueError("You must provide a valid response to continue!")
        except ValueError as error:
            print(error)
            continue
        else:
            break
    return value

#define variables
home = expanduser("~")
logincfg = home+"/.cloginrc"
source_device = input("Please enter network TID (e.g. tamqflpmc6002 or tamrflws4a001): ")
hub_vlans = home+"/"+"hub_vlans"+".cfg"


#let's pull down configuration from TID so script can extract and verify configuration
cmd_one = "show interfaces description | include METRO - Ring"


#run cmd against TID with clogin
output=subprocess.check_output(['clogin', '-f', logincfg, '-c', cmd_one, source_device])
file=open(home+"/"+"hub_vlans"+".cfg", "w")
for i in output.splitlines():
    i=i.decode("utf-8")
    file.write(i+"\n")
file.close

#let's grab a list of only the RING interfaces and put them into a list to determine VLANs configured
ring_int_list = []
with open(hub_vlans) as file_out:
    for interface in file_out:
        if interface.startswith("Gi") or interface.startswith("Te"):
            i=interface.split(" ")
            print(i[0])
            ring_int_list.append(i[0])
print()
print('-' * 232)

#print ring inteface list
print(ring_int_list)
#create a second list to utilize for second command
interface_list = ring_int_list


cmd_two = "show run interface " + str(interface_list)
#let's utilie interface_list to run second command against for VLANs
# for int in list:
#     for interface in interface_list:
#         if ()

这就是我迷失了如何完成这个
