discord - 如果成员为 None，则禁止命令：[discord.py]

Question

@bot.command()
@commands.has_permissions(ban_members=True)
async def ban (ctx, member:discord.User, reason =None):
    if member is None:
        await ctx.channel.send("I have no one to ban")
        return
    if member == ctx.message.author:
        await ctx.channel.send("you can't ban yourself")
        return
    await ctx.guild.ban(member)
    await ctx.channel.send(f"{member} was banned")

这是我的代码

我需要修复：

    if member is None:
        await ctx.channel.send("I have no one to ban")
        return

错误 ：

member 是缺少的必需参数。

像这样将默认值设置member为 None ，那么它将不再是必需的 arg

async def ban (ctx, member:discord.User = None, reason =None):
