我想解析 ifconfig 以便我只剩下分配了 IP 地址的 vlan。 我想要来自每个 vlan 的以下数据、接口(interface)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，我已经为每个 vlan 制作了一个包含 IP 和接口(interface)名称的列表。但是我觉得我偏离了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']]
当前输出:
['vlan1', '0013.F200.0058', '192.168.2.2', 'vlan100', '0013.F200.0058', '192.168.110.2', 'vlan20', '0013.F200.0058', '192.168.30.2']
我知道我可以很容易地将这个平面列表变成嵌套列表，但我觉得应该在这之前的步骤中完成。
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
