Regex在IP和主机名匹配的组中返回错误

Question

下面的脚本通过SSH连接，并在hosts文件中执行CAT命令并收集其中的所有行，之后我尝试将其分为两组IPS和HOSTNAMES数组，删除带有#的注释中的所有内容，但这一在匹配regex时返回了组错误

脚本

#!/usr/bin/python
# -*- coding: utf-8 -*-

from datetime import datetime, date, time, timedelta
import socket
import paramiko
import sys
import re

# create script head
print ('-----------------------------------------------------------------------------------------')
print ('Initializing UP/DOWN script in: '+str(date.today()))
print ('-----------------------------------------------------------------------------------------')

Ips = {'192.168.0.254': {'customer' : 'server'}}

output = []
outfinally = []
arrayIPS = []
arrayHostnames = []

for ip in Ips:

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(hostname=ip, username='root', password="root")
    output.append((ssh.exec_command('cat /opt/hosts.txt')[1]).read().decode())
    ssh.close()

outfinally = [re.split(r'\s*#\s*',line) for line in output[0].splitlines()]

for rows in range(len(outfinally)):
    reg = re.compile(r'^((1?[0-9]{1,2}|2([0-4][0-9]|5[0-5]))\.){3}(1?[0-9]{1,2}|2([0-4][0-9]|5[0-5]))$')
    arrayIPS.append(reg.match(outfinally[rows][0]).groups())

for rows in range(len(outfinally)):
    reg = re.compile(r'^((?!^((1?[0-9]{1,2}|2([0-4][0-9]|5[0-5]))\.){3}(1?[0-9]{1,2}|2([0-4][0-9]|5[0-5]))$).)*$')
    arrayHostnames.append(reg.match(outfinally[rows][0]).groups())

for line in arrayIPS:
    print(line)

输出

Traceback (most recent call last):
  File "collect.py", line 40, in <module>
    arrayHostnames.append(reg.match(outfinally[rows][0]).groups())
AttributeError: 'NoneType' object has no attribute 'groups'
