python - 正则表达式来找到这些值？

Question

我有这样一行:

a = "switchport port-security mac-address 000a.1111.2222 vlan 43"

我想像这样将 mac 和 vlan 编号粘贴到列表中:

["000a.1111.2222","43"]

我认为像下面这样的东西可以做到，有什么想法吗？

import re
a = "switchport port-security mac-address 000a.1111.2222 vlan 43"
b = re.findall("([a-fA-F0-9]{4}[\.]){2}([a-fA-F0-9]{4})|(\d+)",a)
print b

Answer 1

没有正则表达式，只需使用拆分。

a = "switchport port-security mac-address 000a.1111.2222 vlan 43"

split_list = a.split()
required_info = [split_list[3],split_list[5]]
print required_info
>> ["000a.1111.2222","43"]
