Python Rest API-通过字典对象循环

Python Rest API-通过字典对象循环,python,json,rest,dictionary,Python,Json,Rest,Dictionary,这里是Python新手 我正在查询一个API并得到一个json字符串,如下所示: { "human": [ { "h": 310, "prob": 0.9588886499404907, "w": 457, "x": 487, "y": 1053 }, { "h": 283, "prob": 0.8738606572151184, "w": 455, "x":

这里是Python新手

我正在查询一个API并得到一个json字符串,如下所示:

{
  "human": [
    {
      "h": 310,
      "prob": 0.9588886499404907,
      "w": 457,
      "x": 487,
      "y": 1053
    },
    {
      "h": 283,
      "prob": 0.8738606572151184,
      "w": 455,
      "x": 1078,
      "y": 1074
    },
    {
      "h": 216,
      "prob": 0.8639854788780212,
      "w": 414,
      "x": 1744,
      "y": 1159
    },
    {
      "h": 292,
      "prob": 0.7896996736526489,
      "w": 442,
      "x": 2296,
      "y": 1088
    }
  ]
}
for k, v in json_data.iteritems():
    print "{0} : {1}".format(k, v)
def traverse(d):
    for k, v in d.iteritems():
        if isinstance(v, dict):
            traverse(v)
        else:
            print "{0} : {1}".format(k, v)

traverse(json_data)
我知道了如何在python中获取dict对象

json\u data=json.load(response.text)

但是我不知道如何循环dict对象。我已经试过了,但这会反复打印出密钥,如何访问父对象和子对象

   for data in json_data:
        print data
        for sub in data:
            print sub

请参见以下示例:

print json_data['human']
>> [
      {
        "h": 310,
        "prob": 0.9588886499404907,
        "w": 457,
        "x": 487,
        "y": 1053
      },
      {
        "h": 283,
        "prob": 0.8738606572151184,
        "w": 455,
        "x": 1078,
        "y": 1074
      },
      .
      .
  ]


for data in json_data['human']:
    print data
>> {
     "h": 310,
     "prob": 0.9588886499404907,
     "w": 457,
     "x": 487,
     "y": 1053
   } 

   {
     "h": 283,
     "prob": 0.8738606572151184,
     "w": 455,
     "x": 1078,
     "y": 1074
    }
.
.


for data in json_data['human']:
    print data['h']
>> 310
   283
要在按键之间循环,请执行以下操作:

for type_ in json_data:
    print type_
    for location in json_data[type_]:
        print location

type
用于避免Python构建它
type
。您可以使用任何您认为合适的名称。

请参见以下示例:

print json_data['human']
>> [
      {
        "h": 310,
        "prob": 0.9588886499404907,
        "w": 457,
        "x": 487,
        "y": 1053
      },
      {
        "h": 283,
        "prob": 0.8738606572151184,
        "w": 455,
        "x": 1078,
        "y": 1074
      },
      .
      .
  ]


for data in json_data['human']:
    print data

     "h": 310,

     "w": 457,
     "x": 487,
     "y": 1053
   } 

   {
     "h": 283,
     "prob": 0.8738606572151184,
     "w": 455,
     "x": 1078,

我认为您希望使用iteritems从字典中获取键和值,如下所示:

{
  "human": [
    {
      "h": 310,
      "prob": 0.9588886499404907,
      "w": 457,
      "x": 487,
      "y": 1053
    },
    {
      "h": 283,
      "prob": 0.8738606572151184,
      "w": 455,
      "x": 1078,
      "y": 1074
    },
    {
      "h": 216,
      "prob": 0.8639854788780212,

      "x": 1744,
      "y": 1159
    },
    {
      "h": 292,
      "prob": 0.7896996736526489,
      "w": 442,
      "x": 2296,
      "y": 1088
    }
  ]
}
for k, v in json_data.iteritems():
    print "{0} : {1}".format(k, v)
def traverse(d):
    for k, v in d.iteritems():
        if isinstance(v, dict):
            traverse(v)
        else:
            print "{0} : {1}".format(k, v)

traverse(json_data)
如果您打算递归遍历字典,请尝试以下操作:

  "human": [
    {
      "h": 310,
      "prob": 0.9588886499404907,

      "w": 455,
      "x": 1078,
      "y": 1074
    },
    {
      "h": 216,

    }
  ]
}
for k, v in json_data.iteritems():
    print "{0} : {1}".format(k, v)
def traverse(d):

谢谢,但是“钥匙”可以是不同的类型,例如“车辆”、“人”、“建筑”等,我如何循环钥匙,以及如何循环每个钥匙的位置?对不起,如果我的原始问题不清楚。谢谢,但是“钥匙”可以是不同的类型,例如“车辆”、“人”、“建筑”等,我如何循环钥匙以及每个钥匙的循环位置?对不起,如果我的原始问题不清楚的话。对于Python 3,请使用
