在JSON中查找某个对象

import json

    if isinstance(json_data, dict):
        for key, value in json_data.items():
            if key == target_key:

            if result is not None:
                return result

    return None

# 示例JSON数据

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

# 查找名为 "Alice" 的朋友对象
target_object = find_object(json_data, "name")
