关于迭代嵌套json和提取值的指导

import json

def extract_values(data):
    for key, value in data.items():
        if isinstance(value, dict):
            extract_values(value)  # 递归调用，处理嵌套的JSON对象
        else:
            print(key, value)  # 打印键名和对应的值

# 示例JSON数据
json_data = '''
{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 ABC Street",
        "city": "New York",
        "country": "USA"
    },
    "hobbies": ["reading", "music", "sports"]
}
'''

# 解析JSON数据
data = json.loads(json_data)

# 提取值
extract_values(data)
