使用Python解析JSON嵌套字典 [英] Parsing JSON nested Dictionary using Python

问题描述

我在JSON中具有以下嵌套词典.如果要获取"id"，"self"，"name"，应该如何使用Python程序进行解析.

I have the following nested Dictionary in JSON. If I want to get "id", "self", "name", how should I parse it using a Python Program.

{
  "items": [
    {
      "id": "12345",
      "links": {
        "self": "https://www.google.com"
      },
      "name": "beast",
      "type": "Device"
    }
  ],
  "links": {
    "self": "https://www.google.com"
  },
  "paging": {
    "count": 1,
    "limit": 1,
    "offset": 0,
    "pages": 1
  }
}

推荐答案

要了解json的设置方式，将其分解会更容易.让我们看一下第一个字典的键，然后删除值.

To understand how your json is set up, it's easier to break it down. Let's look at the first dictionary's keys, and remove the values.

json = {"items":[]，"links":{}}

您有一本具有两个键和两个值的字典.您要查找的所有三个变量(id，self，name)都在第一个键"items"中.因此，让我们进一步深入.

You have a dictionary with two keys and two values. All three of the variables you are looking for (id, self, name) are in the first key, "items". So let's dive deeper.

json ["items"] = [{'links':{'self':'https://www.google.com'}，'name':'beast'，'type':'设备"，"id":"12345"}]

现在您有了一个包含要查找的值的字典的列表，所以让我们输入包含下一个字典的列表的第一个也是唯一的值.

Now you have a list containing a dictionary with the values you are looking for, so let's enter the first and only value of the list containing the next dictionary.

json ["items"] [0] = {'links':{'self':'https://www.google.com'}，'id':'12345'，'type':'设备'，'名称':'野兽'}

最后，我们有了要查找其值的字典，因此您可以使用此代码查找名称和ID.

Finally we have the dictionary with the values are looking for, so you can use this code to find name and id.

json ["items"] [0] ["name"] =野兽

json ["items"] [0] ["id"] = 12345

自变量在一个字典中更深地被隐藏，因此我们必须深入研究链接键.

The self variable is hidden one dictionary deeper so we have to delve into the links key.

json ["items"] [0] ["links"] ["self"] = http://google.com

现在您拥有了所有的价值，您只需要遵循所有列表和字典来获取所需的价值即可.

Now you have all of your values, you just need to follow through all the lists and dictionaries to get the value you want.
