Python:在JSON中搜索数据

import json

def search_data(json_data, key):
    if isinstance(json_data, dict):
        for k, v in json_data.items():
            if k == key:
                print("找到了匹配的数据：", v)
            elif isinstance(v, (dict, list)):
                search_data(v, key)
    elif isinstance(json_data, list):
        for item in json_data:
            search_data(item, key)

# 示例JSON数据
json_str = '''
{
    "name": "John",
    "age": 30,
    "city": "New York",
    "pets": [
        {
            "name": "Fluffy",
            "type": "cat"
        },
        {
            "name": "Fido",
            "type": "dog"
        }
    ]
}
'''

# 将JSON字符串解析为Python对象
data = json.loads(json_str)

# 在JSON中搜索名为"name"的数据
search_data(data, "name")
