我想解析 ifconfig 以便只剩下分配了 IP 地址的 vlan。我想要每个vlan的以下数据,接口名称,IP地址和mac地址(转换格式的mac)。这些应该存储在列表列表中。每个 vlan 的列表。
到目前为止,我刚刚列出了每个 vlan 的 IP 和接口名称。但是我觉得我正在偏离轨道并且以一种糟糕的方式这样做,有什么建议吗?
期望的输出:
[['vlan1', '192.168.2.2', '0013.F200.0058'], ['vlan100', '192.168.110.2','0013.F200.0058'], ['vlan20', '192.168.30.2','0013.F200.0058']]
电流输出:
['vlan1', '0013.F200.0058', '192.168.2.2', 'vlan100', '0013.F200.0058', '192.168.110.2', 'vlan20', '0013.F200.0058', '192.168.30.2']
我知道我可以轻松地将这个平面列表转换为嵌套列表,但我觉得应该在此之前的步骤中完成。
EG,但我认为这很糟糕:
i=0
new_list=[]
while i<len(data_list):
new_list.append(data_list[i:i+3])
i+=3
