是否可以从不和谐的机器人中打印出 IndexError？

Question

如果执行不正确，我想从我的 Discord 机器人打印出来并 IndexError("List index out of range") 到一个频道。但是，我也用于 AttributeErrors 的方法不起作用。我哪里出错了？

try:
    message = await channel.fetch_message(id_)
except IndexError:
    return await ctx.send('The ID that was entered was incorrect, make sure you have entered the correct giveaway message ID.')

Answer 1

Messageable.fetch_message 从不引发 IndexError，它引发以下内容：

discord.Notfound - 如果找不到消息
discord.Forbidden - 如果您没有所需的权限
discord.HTTPException - 检索消息失败时

回答你的问题 - 你可以简单地排除 discord.NotFound 错误

try:
    message = await channel.fetch_message(message_id)
except discord.NotFound:
    await ctx.send("The ID that was entered is incorrect, make sure you have entered the correct giveaway message ID.")
