我试图用python编写一个不和谐的bot,但它说所有的代码都是错误的?

我不明白为什么?

我的代码:

import discord
from discord.ext import commands

token = ("NTU2NDMzMTIE3NDE4NzYz.D25qlg.O9DZ3Z826EYluNydApWZ3RBjj2Q")

client = commands.Bot(command_prefix="*")

@client.event
async def on_ready():
    print("Bot is ready")

client.run(token)

错误:
