在python中解析没有确定键名的嵌套json

import json

def parse_json(json_data):
    if isinstance(json_data, dict):
        for key, value in json_data.items():
            if isinstance(value, dict) or isinstance(value, list):
                parse_json(value)
            else:
                print(f"键名: {key}，键值: {value}")
    elif isinstance(json_data, list):
        for item in json_data:
            parse_json(item)

# 示例JSON数据
json_str = '''
{
    "name": "John",
    "age": 30,
    "address": {
        "street": "123 Street",
        "city": "New York"
    },
    "hobbies": ["reading", "coding", "gaming"]
}
'''

# 解析JSON数据
json_data = json.loads(json_str)
parse_json(json_data)

键名: name，键值: John
键名: age，键值: 30
键名: street，键值: 123 Street
键名: city，键值: New York
键名: hobbies，键值: ['reading', 'coding', 'gaming']
