如何在对数据库的异步请求中将数据推送到数组？

import asyncio
import aiomysql

async def fetch_data():
    conn = await aiomysql.connect(host='localhost', port=3306,
                                  user='root', password='password',
                                  db='mydatabase', loop=loop)

    cursor = await conn.cursor()
    await cursor.execute("SELECT * FROM mytable")

    data_array = []  # 存储数据的数组

    async for row in cursor:
        data_array.append(row)  # 将每一行数据添加到数组中

    await cursor.close()
    conn.close()

    return data_array

# 使用异步事件循环执行异步函数
loop = asyncio.get_event_loop()
data = loop.run_until_complete(fetch_data())
loop.close()

print(data)
