我有一个来自arista交换机的嵌套字典输出，并且想要迭代此json列表/字典以为每个接口提取以下信息。
Interfacename(like Ethernet29/1)和actorPortPriority(32768)
如何访问此数据？
我试图做：
for k, v in data.items():
print(v['interfaces'])
print(v['interfaces']['actorPortPriority']
但是我不明白。
据我了解，我有一个嵌套的字典，但实际上并没有
遍历嵌套的dict。
data的示例：

您的原始尝试已关闭。
假设json对象的数组称为data。
for item in data:
for k, v in item.get('interfaces').items():
print('Interface Name: {} || Port Priority: {}'.format(k, v.get('actorPortPriority')))
Interface Name: Ethernet29/1 || Port Priority: 32768
Interface Name: Ethernet30/1 || Port Priority: 32768
Interface Name: Ethernet16/1 || Port Priority: 32768
Interface Name: Ethernet11/1 || Port Priority: 0
Interface Name: Ethernet11/2 || Port Priority: 32768

我的解决方案是（如果您要使用其他字典/列表）
In [1]: output = []
...: for interface in data:
...: output.append({k: v['actorPortPriority'] for k, v in interface['interfaces'].items()})
...:
In [2]: output
Out[2]:
[{'Ethernet29/1': 32768, 'Ethernet30/1': 32768},
{'Ethernet16/1': 32768},
{'Ethernet11/1': 0, 'Ethernet11/2': 32768}]
如果你想要一个字典
In [3]: output = {}
...: for interface in data:
...: output.update({k: v['actorPortPriority'] for k, v in interface['interfaces'].items()})
...:
In [4]: output
Out[4]:
{'Ethernet11/1': 0,
'Ethernet11/2': 32768,
'Ethernet16/1': 32768,
'Ethernet29/1': 32768,
'Ethernet30/1': 32768}

您可以使用：
for v in data:
for interface, info in v['interfaces'].items():
print(interface)
print(info['actorPortPriority'])
