Python 打印JSON元素

关于如何打印JSON元素，我有点不明白。有了Yelp，多亏了这个查询“”，我可以检索这个JSON:

{
  "businesses": [
    {
      "id": "gaumont-wilson-toulouse-2",
      "name": "Gaumont Wilson",
      "image_url": "https://s3-media1.fl.yelpcdn.com/bphoto/dYJc874NnEJ9-jX2amrLvw/o.jpg",
      "is_closed": false,
      "url": "https://www.yelp.com/biz/gaumont-wilson-toulouse-2?adjust_creative=Xi9rQmCT871UpMvNRzAfuw&utm_campaign=yelp_api_v3&utm_medium=api_v3_business_search&utm_source=Xi9rQmCT871UpMvNRzAfuw",
      "review_count": 165,
      "categories": [
        {
          "alias": "movietheaters",
          "title": "Cinema"
        }
      ],
      "rating": 4,
      "coordinates": {
        "latitude": 43.6044154,
        "longitude": 1.4475916
      },
      "transactions": [],
      "location": {
        "address1": "3 place du Président Thomas Wilson",
        "address2": null,
        "address3": null,
        "city": "Toulouse",
        "zip_code": "31000",
        "country": "FR",
        "state": "31",
        "display_address": [
          "3 place du Président Thomas Wilson",
          "31000 Toulouse",
          "France"
        ]
      },
      "phone": "+33534445050",
      "display_phone": "+33 5 34 44 50 50",
      "distance": 451.43923036020004
    }
  ],
  "total": 11,
  "region": {
    "center": {
      "latitude": 43.602510035320684,
      "longitude": 1.4426422119140625
    }
  }
}

然后我通过以下方式研究JSON：

response_data = response.json()
for i in response_data['businesses']:
    print i['name']

但是

“name”

是我唯一可以打印的东西

我无法打印

'address1'

，

'city'

或

'zip\u code'

---

为什么？

因为这些键在JSON的层次结构中不存在。它们存在于字典中的

“location”

键上。您希望使用：

print i["name"]["location"]["address1"]

---

因为它们存在于“位置”子字典中。你需要这样的东西：

打印i[“名称”][“位置”][“地址1”]

访问数据。

答案是：

for element in response_data['businesses']:
    id = element['id']
    name = element['name']
    city = element['location']['city']
    zip_code = element['location']['zip_code']
    state = element['location']['state']
    display_address = element['location']['display_address']
    latitude = element['coordinates']['latitude']
    longitude = element['coordinates']['longitude']
    phone = element['phone']

    print id, name,  city, zip_code, state, display_address, latitude, longitude, phone

只是一个注释——它实际上不是一个JSON对象。这是一本字典，正如你所发现的，它有点不同。
