for 循环在我的 discord.py 机器人中运行得太快

Question

我有一个 for 循环，它遍历一个问题列表，为每个问题创建一个嵌入。这意味着然后等待答案，然后问下一个问题。然后我将答案上传到 mongodb 数据库（在运行一些检查以确保它们是有效答案之后。

我遇到的问题是，有时（10 次尝试中的 3 次）它会一个接一个地问两个问题，而没有时间回答第一个问题。我玩过 sleep() 但发现它仍然会发生。

如果您能提供任何帮助，我们将不胜感激！

我以前见过这个错误，它发生在机器人消息发送速度足够快以通过检查时，很容易修复，只需确保只有你可以回复消息

# add this
def check(message):
    channel_id = message.channel.id
    author_id = message.author.id
    return channel_id == ctx.channel.id and author_id == ctx.author.id

# change this
reaction, member = await self.bot.wait_for(
    "reaction_add",
    timeout=60,
    check=check
)
