如何将相同的名称值格式化为数组

Question

我有这个JSON数据

  {
    "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"
        ]
      }
    ]
  }
]

我想将"Roles"中的所有"Roles"格式化为一个数组，然后打印。我只能使用代码打印第一个“名称”

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

我怎样才能把它格式化以便打印出来

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

然后将该数据保存在数组中，以便用于另一个函数，该函数将充当

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

只需对循环中的每个值执行请求。

Answer 1

您可以使用对Roles数据集的列表理解来获取Name属性：

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

输出(用于样本数据)：

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

Answer 2

jsonpath 包专门用于处理json数据.。

你只需要学习一些简单的语法就可以操作了。

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"))

输出

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