在我的例子中，如何从DB中检索数据并将其转换为对象？

import mysql.connector

# 连接数据库
cnx = mysql.connector.connect(user='your_username', password='your_password',
                              host='your_host', database='your_database')

# 创建游标对象
cursor = cnx.cursor()

# 执行查询
query = "SELECT * FROM your_table"
cursor.execute(query)

# 获取结果集
result_set = cursor.fetchall()

# 转换为对象
class DataObject:
    def __init__(self, id, name, age):
        self.id = id
        self.name = name
        self.age = age

data_objects = []
for row in result_set:
    data_object = DataObject(row[0], row[1], row[2])
    data_objects.append(data_object)

# 存储对象
for obj in data_objects:
    print(obj.id, obj.name, obj.age)

# 关闭游标和数据库连接
cursor.close()
cnx.close()
