如何將相同名稱的值格式化為數組

Question

我有這個 JSON 數據

  {
    "Label": "Color Roles",
    "Pool": "Colors",
    "Hidden": false,
    "Limit": -3,
    "Message": "Pick a colored role to start with <3",
    "Roles": [
      {
        "Name": "Apple★",
        "Print": "Apple",
        "Aliases": ".iam Apple",
        "Aliases1": [
          ".iam Apple",
          "+Apple"
        ]
      },
      {
        "Name": "Clementine★",
        "Print": "Clementine",
        "Aliases": [
          ".iam Clementine",
          "+Clementine"
        ]
      },
      {
        "Name": "Sunflower★",
        "Print": "Sunflower",
        "Aliases": [
          ".iam Sunflower",
          "+Sunflower"
        ]
      },
      {
        "Name": "Mint★",
        "Print": "Mint",
        "Aliases": [
          ".iam Mint",
          "+Mint"
        ]
      },
      {
        "Name": "Ocean★",
        "Print": "Ocean",
        "Aliases": [
          ".iam Ocean",
          "+Ocean"
        ]
      },
      {
        "Name": "Grape★",
        "Print": "Grape",
        "Aliases": [
          ".iam Grape",
          "+Grape"
        ]
      },
      {
        "Name": "Candy Floss★",
        "Print": "Candy Floss",
        "Aliases": [
          ".iam Candy Floss",
          "+Candy Floss"
        ]
      }
    ]
  }
]

我想將"Roles"中的所有"Name ”格式化為一個數組然后打印。我只能使用代碼打印第一個“名稱”

print(data['roles'][0]['name'])

我怎樣才能讓它格式化以便打印

["Apple★","Clementine★","Sunflower★","Mint★","Ocean★","Grape★","Candy Floss★"]

然后將該數據保存在數組中以用於另一個功能，該功能將充當

values = ["Apple★","Clementine★","Sunflower★","Mint★","Ocean★","Grape★","Candy Floss★"]
info = requests.get(https://api.url.com/{Values?}

只是對循環中的每個值進行請求

Answer 1

您可以對Roles dicts 使用列表理解來獲取Name屬性：

values = [role['Name'] for role in data['Roles']]

輸出（用於您的樣本數據）：

["Apple★", "Clementine★", "Sunflower★", "Mint★", "Ocean★", "Grape★", "Candy Floss★"]

Answer 2

jsonpath包專用於 python 處理 json 數據。

您只需要學習一些簡單的語法即可進行操作。

from jsonpath import jsonpath

data = {
    "Label": "Color Roles",
    "Pool": "Colors",
    "Hidden": "false",
    "Limit": -3,
    "Message": "Pick a colored role to start with <3",
    "Roles": [
      {
        "Name": "Apple★",
        "Print": "Apple",
        "Aliases": ".iam Apple",
        "Aliases1": [
          ".iam Apple",
          "+Apple"
        ]
      },
      {
        "Name": "Clementine★",
        "Print": "Clementine",
        "Aliases": [
          ".iam Clementine",
          "+Clementine"
        ]
      },
      {
        "Name": "Sunflower★",
        "Print": "Sunflower",
        "Aliases": [
          ".iam Sunflower",
          "+Sunflower"
        ]
      },
      {
        "Name": "Mint★",
        "Print": "Mint",
        "Aliases": [
          ".iam Mint",
          "+Mint"
        ]
      },
      {
        "Name": "Ocean★",
        "Print": "Ocean",
        "Aliases": [
          ".iam Ocean",
          "+Ocean"
        ]
      },
      {
        "Name": "Grape★",
        "Print": "Grape",
        "Aliases": [
          ".iam Grape",
          "+Grape"
        ]
      },
      {
        "Name": "Candy Floss★",
        "Print": "Candy Floss",
        "Aliases": [
          ".iam Candy Floss",
          "+Candy Floss"
        ]
      }
    ]
  }

print(jsonpath(data, "$..Name"))

出去

['Apple★', 'Clementine★', 'Sunflower★', 'Mint★', 'Ocean★', 'Grape★', 'Candy Floss★']
