목록으로 ifconfig 구문 분석

Question

ifconfig를 구문 분석하여 IP 주소가 할당 된 VLAN 만 남겨두고 싶습니다. 각 VLAN, 인터페이스 이름, IP 주소 및 MAC 주소 (변환 된 형식의 Mac)에서 다음 데이터를 원합니다. 이들은 목록의 목록에 저장되어야합니다. 각 VLAN에 대한 목록입니다.

지금까지 각 VLAN에 대해 IP 및 인터페이스 이름으로 하나의 목록을 만들었습니다. 그러나 나는 궤도에서 벗어나서 나쁜 생각으로 어떤 제안을하고 있다고 느낍니까?

원하는 출력 :

[['vlan1', '192.168.2.2', '0013.F200.0058'], ['vlan100', '192.168.110.2','0013.F200.0058'], ['vlan20', '192.168.30.2','0013.F200.0058']] 

전류 출력 :

['vlan1', '0013.F200.0058', '192.168.2.2', 'vlan100', '0013.F200.0058', '192.168.110.2', 'vlan20', '0013.F200.0058', '192.168.30.2'] 

내가 쉽게 중첩 된 목록으로이 단순 목록을 설정할 수 있습니다 알고 있지만, 나는 그것이이 전 단계에서 수행해야합니다 생각합니다.

EG는하지만이 나쁜 생각 :

이

i=0 
new_list=[] 
while i<len(data_list): 
    new_list.append(data_list[i:i+3]) 
    i+=3 

코드 :
