使用 Python 读取深度嵌套的 Json 对象

Question

I want to read the value of a deeply nested Json object. I am interested in reaching the temperature value.

{
    "weatherChannel": [
       {
           "week": {  
                "location": [
                    {
                        "info": [ 
                            {
                                "temperature": 5
                            }
                         ]
                     }
                 ]
            } 
        }
     ]
 }

I am capable of reaching the location information by doing: weatherChannel['week']['location'] but I am unable to go further down.

Any suggestions on how this can be achieved would be appreciated.

Answer 1

d = {
     "weatherChannel": [
        {
            "week": {  
                 "location": [
                     {
                         "info": [ 
                             {
                                 "temperature": 5
                             }
                          ]
                      }
                  ]
             } 
         }
      ]
  }

d["weatherChannel"][0]["week"]["location"][0]["info"][0]["temperature"]

That provides what you need. You need to understand that [] denotes List and you access to List elements through their position (first position is 0, not 1). While {} denotes dictionary which contains pairs key:value like for example "temperature":5 and you access the values through their keys.

Answer 2

weatherChannel 包含一个列表，因此将是weatherChannel[0]["week"]["location"]
