不管密钥的位置如何,都更新字典值

可以这样做:

data = {
    'record': 'Nicaragua',
    'text': 'Hello World!',
    'latitude': 10.1,
    'longitude': 122.55,
    'address': None
}

model = {
    "record": "Germany",
    "text": "<br>",
    "map": {
        "latitude": 0.0,
        "longitude": 0.0
    }
}


def r_update(target, key, value):
    if key in target:
        target[key] = value
    else:
        for k, v in target.items():
            if isinstance(v, dict):
                r_update(v, key, value)


def update(source, target):
    for key, value in source.items():
        r_update(target, key, value)


update(data, model)
print(model)

输出

{'record': 'Nicaragua', 'text': 'Hello World!', 'map': {'longitude': 122.55, 'latitude': 10.1}}
