如何使json对象的键成为该对象中某一项的值？

Question

现在，我的.json文件中的一个对象如下所示：

{
    "id": 1,
    "name": "Bulbasaur",
    "type_1": "Grass",
    "type_2": "Poison",
    "primary_color": "Green",
    "height": 0.7,
    "weight": 6.9,
    "hp": 45,
    "attack": 49,
    "defense": 49,
    "speed": 45,
    "can_evolve": "TRUE",
    "evolves_from": "",
    "final_evolution": "FALSE",
    "mega_evolution": "FALSE"
},

我想要一种将上面的json的多个副本(900份)转换成这样的方法：

{
    "1": [
        {
            "name": "Bulbasaur",
            "type_1": "Grass",
            "type_2": "Poison",
            "primary_color": "Green",
            "height": 0.7,
            "weight": 6.9,
            "hp": 45,
            "attack": 49,
            "defense": 49,
            "speed": 45,
            "can_evolve": "TRUE",
            "evolves_from": "",
            "final_evolution": "FALSE",
            "mega_evolution": "FALSE"
        }
    ],
    "Bulbasaur": [
        {
            "id": "1",
            "type_1": "Grass",
            "type_2": "Poison",
            "primary_color": "Green",
            "height": 0.7,
            "weight": 6.9,
            "hp": 45,
            "attack": 49,
            "defense": 49,
            "speed": 45,
            "can_evolve": "TRUE",
            "evolves_from": "",
            "final_evolution": "FALSE",
            "mega_evolution": "FALSE"
        }
    ]
}

实际上，我只需要找到一种方法，将对象的键设置为同一个对象的值，我就可以设置好了。

谢谢!

使用dict.fromkeys()

original = {
    "id": 1,
    "name": "Bulbasaur",
    "type_1": "Grass",
    "type_2": "Poison",
    "primary_color": "Green",
    "height": 0.7,
    "weight": 6.9,
    "hp": 45,
    "attack": 49,
    "defense": 49,
    "speed": 45,
    "can_evolve": "TRUE",
    "evolves_from": "",
    "final_evolution": "FALSE",
    "mega_evolution": "FALSE"
}

result = dict.fromkeys((original['id'], original['name']), original)

result是：

{1: {'attack': 49,
     'can_evolve': 'TRUE',
     'defense': 49,
     'evolves_from': '',
     'final_evolution': 'FALSE',
     'height': 0.7,
     'hp': 45,
     'id': 1,
     'mega_evolution': 'FALSE',
     'name': 'Bulbasaur',
     'primary_color': 'Green',
     'speed': 45,
     'type_1': 'Grass',
     'type_2': 'Poison',
     'weight': 6.9},
 'Bulbasaur': {'attack': 49,
               'can_evolve': 'TRUE',
               'defense': 49,
               'evolves_from': '',
               'final_evolution': 'FALSE',
               'height': 0.7,
               'hp': 45,
               'id': 1,
               'mega_evolution': 'FALSE',
               'name': 'Bulbasaur',
               'primary_color': 'Green',
               'speed': 45,
               'type_1': 'Grass',
               'type_2': 'Poison',
               'weight': 6.9}}
