如何通过属性在嵌套对象中搜索对象，并返回带有父对象的键和值的对象？

def search_nested_object(obj, target):
    result = {}
    for key, value in obj.items():
        if isinstance(value, dict):
            nested_result = search_nested_object(value, target)
            if nested_result:
                result[key] = nested_result
        elif value == target:
            result[key] = value
    return result

nested_obj = {
    'a': {
        'b': {
            'c': 1,
            'd': 2
        },
        'e': {
            'f': 3,
            'g': 4
        }
    },
    'h': {
        'i': {
            'j': 5,
            'k': 6
        },
        'l': {
            'm': 7,
            'n': 8
        }
    }
}

target_value = 4
result = search_nested_object(nested_obj, target_value)
print(result)

{
    'a': {
        'e': {
            'g': 4
        }
    }
}
