如何映射和过滤低于某个数字的JSON嵌套数据字典？

import json

def filter_json_data(data, threshold):
    if isinstance(data, dict):
        for key, value in list(data.items()):
            if isinstance(value, (int, float)):
                if value < threshold:
                    del data[key]
            elif isinstance(value, (dict, list)):
                filter_json_data(value, threshold)
    elif isinstance(data, list):
        for item in data:
            filter_json_data(item, threshold)
            
# 示例数据
json_data = {
    "name": "John",
    "age": 30,
    "scores": [85, 90, 70],
    "address": {
        "street": "123 Main St",
        "city": "New York",
        "zipcode": "10001"
    }
}

# 过滤阈值为80以下的数据
filter_json_data(json_data, 80)

# 打印过滤后的数据
print(json.dumps(json_data, indent=4))
