IP アドレスが割り当てられている VLAN のみが残るように、ifconfig を解析したいと考えています。各 vlan から次のデータ、インターフェイス名、IP アドレス、および MAC アドレス (変換された形式の mac) が必要です。これらは、リストのリストに格納する必要があります。各 VLAN のリスト。

これまでのところ、各 VLAN の IP とインターフェイス名を含む 1 つのリストを作成しました。しかし、私は軌道から外れており、これを悪い方法で行っていると感じています。何か提案はありますか?

望ましい出力:

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

現在の出力:

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

このフラット リストをネストされたリストに簡単に変換できることはわかっていますが、この前のステップで行う必要があると感じています。

EGしかし、これは悪いと思います：

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