python json dict iterate {key:value}是一样的

Question

我有一个我正在阅读的json文件; 看起来类似于:

[
  {
    "Destination_IP": "8.8.4.4",
    "ID": 0,
    "Packet": 105277
  },
  {
    "Destination_IP": "9.9.4.4",
    "ID": 0,
    "Packet": 105278
  }
]

当我解析json时:

for json_dict in data:
    for key,value in json_dict.iteritems():
        print("key: {0} | value: {0}".format(key, value))

我正进入(状态:

key: Destination_IP | value: Destination_IP

我已经尝试使用.items(),我已经尝试过通过遍历键iterkeys()和keys()无济于事.

我可以直接调用它json_dict['Destination_IP']并返回值.

for json_dict in data:
    if 'Destination_IP' in json_dict.keys():
        print json_dict['Destination_IP']

收益:

key: Destination_IP | value: 8.8.4.4

我在python 2.7上,所以在运行值部分的任何帮助都将非常感激.

更改字符串格式索引:

for json_dict in data:
    for key,value in json_dict.iteritems():
        print("key: {0} | value: {1}".format(key, value))

或者不使用索引:

for json_dict in data:
    for key,value in json_dict.iteritems():
        print("key: {} | value: {}".format(key, value))

您也可以使用名称而不是索引:

for json_dict in data:
    for key,value in json_dict.iteritems():
        print("key: {key} | value: {value}".format(key=key, value=value))
