python中按IP地址和字符串顺序降序排列列表

我有一个字符串列表，如下所示：

ip route vrf t141 0.0.0.0/0 10.76.102.101 name edge
ip route vrf t141 10.0.0.0/8 10.76.101.101
ip route vrf t141 172.16.0.0/12 10.76.101.101
ip route vrf t141 192.168.0.0/16 10.76.101.101
ip route vrf t141 29.0.0.0/8 10.76.101.101
ip route vrf t20 0.0.0.0/0 10.76.102.27
ip route vrf t20 10.0.0.0/8 10.76.101.27
ip route vrf t20 172.16.0.0/12 10.76.101.27
ip route vrf t20 192.168.0.0/16 10.76.101.27
ip route vrf t20 29.0.0.0/8 10.76.101.27

我需要按vrf名称（t141，t20）的降序以及IP地址的降序对列表进行排序<代码>排序和

排序

在基于vrf名称对字符串进行排序时工作正常，但在IP地址上工作不正常：行

IP路由vrf t141 29.0.0.0/8 10.76.101.101

应位于

IP路由vrf t141 10.0.0.0/8 10.76.101.101

之后，以及

IP路由vrf t20 29.0.0.0/8 10.76.101.27

之后位于

ip路由vrf t20 10.0.0.0/8 10.76.101.27之后，不在底部

这里是更好阅读的区别

 ip route vrf t10 0.0.0.0/0 10.76.102.25
 ip route vrf t10 10.0.0.0/8 10.76.101.25
+ip route vrf t10 29.0.0.0/8 10.76.101.25
 ip route vrf t10 172.16.0.0/12 10.76.101.25
 ip route vrf t10 192.168.0.0/16 10.76.101.25
-ip route vrf t10 29.0.0.0/8 10.76.101.25
 ip route vrf t141 0.0.0.0/0 10.76.102.101 name edge
 ip route vrf t141 10.0.0.0/8 10.76.101.101
+ip route vrf t141 29.0.0.0/8 10.76.101.101
 ip route vrf t141 172.16.0.0/12 10.76.101.101
 ip route vrf t141 192.168.0.0/16 10.76.101.101
-ip route vrf t141 29.0.0.0/8 10.76.101.101

非常感谢您的任何建议
您可以使用正则表达式在排序方法中实现此结果

import re

ls = ['ip route vrf t141 0.0.0.0/0 10.76.102.101 name edge',
'ip route vrf t141 10.0.0.0/8 10.76.101.101',
'ip route vrf t141 172.16.0.0/12 10.76.101.101',
'ip route vrf t141 192.168.0.0/16 10.76.101.101',
'ip route vrf t141 29.0.0.0/8 10.76.101.101',
'ip route vrf t20 0.0.0.0/0 10.76.102.27',
'ip route vrf t20 10.0.0.0/8 10.76.101.27',
'ip route vrf t20 172.16.0.0/12 10.76.101.27',
'ip route vrf t20 192.168.0.0/16 10.76.101.27',
'ip route vrf t20 29.0.0.0/8 10.76.101.27']


print(*sorted(ls, key=lambda x: (int(re.search(r"(?:vrf t)(\w*)", x).group(1)), " ".join([i for i in x.split(" ") if not re.sub("[0-9.\/]", "", i)]))), sep="\n")

输出

ip route vrf t20 0.0.0.0/0 10.76.102.27
ip route vrf t20 10.0.0.0/8 10.76.101.27
ip route vrf t20 172.16.0.0/12 10.76.101.27
ip route vrf t20 192.168.0.0/16 10.76.101.27
ip route vrf t20 29.0.0.0/8 10.76.101.27
ip route vrf t141 0.0.0.0/0 10.76.102.101 name edge
ip route vrf t141 10.0.0.0/8 10.76.101.101
ip route vrf t141 172.16.0.0/12 10.76.101.101
ip route vrf t141 192.168.0.0/16 10.76.101.101
ip route vrf t141 29.0.0.0/8 10.76.101.101

t20
应该在
t141
之前还是之后排序？您想要什么并不清楚。您想按字母顺序排序（“t141”<“t20”和“172”<“29”）还是使用字符串中的数字（表示t141>t20和172>29）？
