如何使用循环更新数据库？

尝试让机器人每秒检查一次数据库，如果有人有 800 XP，就把他们的等级改成'Elite Genin'。

  @bot.event
async def on_ready():
    print(f"Logged in as: {bot.user.name}")

    if not loop.is_running():
        loop.start()


@tasks.loop(seconds = 1)
async def loop(ctx):
    guild = ctx.guild.id
    table = "PEOPLE_" + str(guild)

    try:
        connection = mysql.connector.connect(
        host="localhost",
        port="3306",
        user="root",
        password="root",
        database="naruto_game"
        )
        cursor = connection.cursor()
    except mysql.connector.Error as error:
        print("Failed to find name: {}".format(error))
    finally:
        print(f"Logged in as: {bot.user.name}")

    sql_update_query = "UPDATE " + table + "SET rank = 'Elite Genin' where xp = 800"
    cursor.execute(sql_update_query)

错误提示：

TypeError: loop() missing 1 required positional argument: 'ctx'
