当用户的消息以问号结尾时，如何让机器人说些什么？

Question

@client.command(aliases=["ques", "q", "8ball", "QUES", "Q", "8BALL"])
async def question(ctx):
    answer = "yes", "no", "idk"
    final_answer = random.choice(answer)

    await ctx.send("Please ask a yes or no question")
    msg = await client.wait_for("message")

    if ctx.content.endswith("?"):
        await ctx.send(final_answer)
    else:
        await ctx.send("That's not a question!")

所以我想为我的discord机器人添加一个功能，用于8ball。但是我想让机器人找出发送的文本是否是一个问题。我在这里使用endswith属性，但它显示

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: AttributeError: 'Context' object has no attribute 'content'```

可以肯定的是，这个错误本身就说明了，Context没有content属性。您在await client.wait_for(...)中定义了msg，应该使用该变量而不是ctx

@client.command(aliases=["ques", "q", "8ball", "QUES", "Q", "8BALL"])
async def question(ctx):
    answer = "yes", "no", "idk"
    final_answer = random.choice(answer)

    await ctx.send("Please ask a yes or no question")
    msg = await client.wait_for("message")

    if msg.content.endswith("?"):
        await ctx.send(final_answer)
    else:
        await ctx.send("That's not a question!")
