python - 在 Python 中循环遍历 JSON 数组

Question

我从 API 中获取了以下数据。我正在尝试使用 Python 脚本访问餐厅名称并让脚本显示它。这是我的文件:

测试.py

with open('data.json') as data_file:    
    data = json.load(data_file)
    for restaurant in data:
        print data ['restaurants'][0]['restaurant']['name']

我的JSON文件如下:(简化)

    {
  "results_found": 3296,
  "results_start": 0,
  "results_shown": 20,
  "restaurants": [
    {
      "restaurant": {
        "R": {
          "res_id": 9101083
        },
        "id": "9101083",
        "name": "My Meat Wagon",
          "address": "Market Square, Smithfield, Dublin Dublin 7",

        "establishment_types": []
      }
    },
    {
      "restaurant": {
        "R": {
          "res_id": 9101628
        },
        "id": "9101628",

          "zipcode": "Dublin 2",
          "country_id": 97,
          "locality_verbose": "The Workmans Club, Dublin"
        },
        "switch_to_order_menu": 0,
        "cuisines": "Burger",
        "average_cost_for_two": 20,
        "establishment_types": []
      }
    },
    {
      "restaurant": {
        "R": {
          "res_id": 16520426
        },
        "id": "16520426",
        "name": "Brother Hubbard",
          "locality_verbose": "North City, Dublin"
        },

目前，它会显示第一个餐厅名称 3 次。我希望它遍历每个 restaurant 对象并显示键“name”的值。任何帮助，将不胜感激。

当 restaurants 是您的列表时，您必须迭代此键:

for restaurant in data['restaurants']:
    print restaurant['restaurant']['name']
