如何将嵌套的json属性赋值给父对象？

def assign_nested_json(json_obj, parent_obj):
    for key, value in json_obj.items():
        if isinstance(value, dict):
            assign_nested_json(value, parent_obj[key])
        else:
            parent_obj[key] = value

# 示例用法
nested_json = {
    "name": {
        "first": "John",
        "last": "Doe"
    },
    "age": 30
}

parent_obj = {
    "name": {
        "first": "",
        "last": ""
    },
    "age": 0
}

assign_nested_json(nested_json, parent_obj)
print(parent_obj)

{
    "name": {
        "first": "John",
        "last": "Doe"
    },
    "age": 30
}
