从python dict更改嵌套json结构

我有一个巨大的JSON文件：

substitutions.JSON

，看起来像这样：

[
    {
        "city":"05045",
        "tribunals":[
            {"name":"tribunal 1","value":"path_1"}
            ]
    },
    {
        "city":"81001",
        "tribunals":[
            {"name":"tribunal 1","value":"path_1"},
            {"name":"tribunal 2","value":"path_2"},
            {"name":"tribunal 3","value":"path_3"},
            {"name":"tribunal 4","value":"path_4"},
            {"name":"tribunal 5","value":"path_5"},
            {"name":"tribunal 6","value":"path_6"}
            ]
    }
]

我想把它转换成这样：

{
    "05045": 
    {
        "tribunal 1": "path_1"
    },
    "81001":
    {
        "tribunal 1": "path_1",
        "tribunal 2": "path_2",
        "tribunal 3": "path_3",
        "tribunal 4": "path_4",
        "tribunal 5": "path_5",
        "tribunal 6": "path_6"
    }
}

我尝试了JSON上的不同类型的迭代以获得预期的输出，但没有一种有效。就目前而言，我正在这样做：

import json
tribunals = open('tribunals.json',encoding='utf-8')
tribunals = json.load(tribunals)

for tribunal in tribunals:
    print(tribunal['city'])
    for tribunals_list in tribunal['tribunals']:
        print(tribunals_list)

这给了我下一个输出

05045
{"name":"tribunal 1", "value":"path_1"}
81001
{"name":"tribunal 1","value": "path_1"}
{"name":"tribunal 2","value": "path_2"}
{"name":"tribunal 3","value": "path_3"}
{"name":"tribunal 4","value": "path_4"}
{"name":"tribunal 5","value": "path_5"}
{"name":"tribunal 6","value": "path_6"}

基于此，我将使用文本编辑器完成这项工作，但显然，最好的选择是完全用脚本完成这项工作。有什么建议吗

谢谢

为什么要打印而不是把它变成你要的字典？@Sayse，这是我尝试过的，但我不知道怎么做，这就是我把它贴在这里的原因。也许它需要在代码中稍作修改，但我已经试了几个小时没有实现它！为什么要打印而不是把它变成你要的字典？@Sayse，这是我尝试过的，但我不知道怎么做，这就是为什么要把它贴在这里。也许它需要在代码中稍作修改，但我已经试了几个小时没有实现它！谢谢那正是我想要的！谢谢那正是我想要的！

import json

tribunals = json.load(tribunals)

result = {}

for tribunal in tribunals:

    for item in tribunal['tribunals']:

print(result)
