Python中如何动态修改嵌套JSON请求负载的值？

{
    "shopattrresplist": [
        {
            "child": [
                {
                    "child": [
                        {
                            "value": "{{\"address\":\"{{address}}\",\"longitude\":{longitude},\"latitude\":{latitude},\"province\":{province},\"city\":{city},\"region\":{region}}}",
                            "xxxx": "yyy"
                        }
                    ]
                }
            ]
        }
    ]
}

replacement_map = {
    "金花街道高第坊39号荔湾区金花街锦绣社区": address,  # 替换 address 值
    "113.252272": longitude,  # 替换 longitude 值
    # ... 其他变量的替换
}

for key, value in replacement_map.items():
    data["shopattrresplist"][0]["child"][0]["child"][0]["value"] = data["shopattrresplist"][0]["child"][0]["child"][0]["value"].replace(key, value)

data["shopAttrRespList"][0]["child"][0]["child"][0]["value"] = json.dumps(data["shopAttrRespList"][0]["child"][0]["child"][0]["value"])
