有没有办法将嵌套的 json 数组转换为多个数组？ [复制]

Question

有没有办法转换一个看起来像这样的json：

{
    "id": "1",
    "object": [{
        "object_1": "hi",
        "object_2": "hello"
    },
    {
        "object_1": "hello",
        "object_2": "hi"
    }]
}

到我可以在每个字典中存储父 ID 而不必像这样更改名称的地方？

{
"id": "1",
"object_1": "hi",
"object_2": "hello"
},
{"id": "1",
"object_1": "hi",
"object_2": "hello"
}

Answer 1

有很多方法可以转换字典。例如，使用生成器：

d = {
    "id": "1",
    "object": [{
        "object_1": "hi",
        "object_2": "hello"
    },
    {
        "object_1": "hello",
        "object_2": "hi"
    }]
}
    
def flatten_dict(d):
    for o in d['object']:
        yield {
            'id': d['id'],
            **o
        }

print(list(flatten_dict(d)))

打印：

[{'id': '1', 'object_1': 'hi', 'object_2': 'hello'}, {'id': '1', 'object_1': 'hello', 'object_2': 'hi'}]
