python - 替换嵌套字典值

Question

1. 我从我的示例数据框创建了一个嵌套字典：

dict_1 = {
    "AR": {
        "tom": {"q": 1.0},
        "jerry": {"q": 1.0},
        "spike": {"q": 1.0}
    },
    "DB": {
        "goku": {"q": 1.0},
        "vegeta": {"q": 2.0},
        "gohan": {"q": 1.0},
        "trunks": {"q": 1.0},
    },
}

2. 我有另一本字典：

dict_2 = {
    "AR": {
        "tom": {"q": 1.0}
    },
    "DB": {
        "goku": {"q": 1.0}
    },
}

3. 现在我想检查字典 1 并想替换 dict_2 中的 dict_1 的相同值。输出应该是：

dict_3 = dict_2 + {
    "AR": {"jerry": {"q": 1.0}, "spike": {"q": 1.0}},
    "DB": {"vegeta": {"q": 2.0}, "gohan": {"q": 1.0}, "trunks": {"q": 1.0}},
}
