Python ValueError应为2，但得到了1个discord.py

我试图让它检查，如果用户已经取消，然后再发送消息，他们已经取消退火。但我一直在犯错误

下面是确切的错误：

    @commands.command()
    @has_permissions(ban_members=True)
    async def unban(self, ctx, *, member):

        embed = discord.Embed(title="Unban", description=f"Unbanned - {member}", colour=discord.Colour.purple())

        banned_users = await ctx.guild.bans()
        member_name, member_discriminator = member.split('#')

        for ban_entry in banned_users:
            user = ban_entry.user

            if (user.name, user.discriminator) == (member_name, member_discriminator):
                await ctx.guild.unban(user)

                if (member_name, member_discriminator) in banned_users:
                    await ctx.send(f'Error unbanning {member.mention}.')
                    return
                else:
                    pass

                await ctx.send(embed=embed)
                print(f'{current_time} {member} has been unbanned by @{ctx.message.author}. Server Name: {ctx.guild.name}, Server ID: {ctx.guild.id}\n')
                with open('textfiles/text-logs/unban-log.txt', 'a') as unbanlog:
                    unbanlog.writelines(f'{current_time} {member} has been unbanned by @{ctx.message.author}. Server Name: {ctx.guild.name}, Server ID: {ctx.guild.id}\n')
                return

我建议将member参数转换为member对象，如下所示。然后，您可以将

discord.Member

对象的属性用于鉴别器等

async def unban（self、ctx、member:commands.MemberConverter）：

您可以通过执行

member.discriminator

检索鉴别器，并使用

member.name

检索其名称。看看这本书

我还建议只检查用户和成员是否相同，而不是检查他们的鉴别器和名称

如果用户==成员：

如果取消扫描不起作用，还应该删除异常处理。这是因为如果它没有正确地取消ban，它将自动引发一个错误

然后，在末尾的字符串中，将

member

转换为键入字符串，使其可读

总体而言，实施情况如下所示：

Ignoring exception in on_command_error
Traceback (most recent call last):
  File "C:\Users\ajkit\AppData\Local\Programs\Python\Python39\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)

    member_name, member_discriminator = member.split('#')

The above exception was the direct cause of the following exception:

这意味着

成员

参数中没有一个

“#”

，那么我会改变什么呢？当我完成所有这些时，它会完全改变breaks@Axkkzy嗯，奇怪，让我试着把整个实现。谢谢！我不知道转换器是如何工作的，所以我还有很长的路要走。谢谢你帮我
