我试图使它的地方，机器人将告诉你指定一个成员静音，如果他们没有指定它。我该怎么做？我试过但没有效果

Question

下面的静音代码。如果一个mod没有指定要静音的成员，机器人怎么能告诉他们呢？谢谢！

@bot.command()
@commands.has_permissions(manage_roles=True)
async def mute(ctx, member: discord.Member, reason=None):
   
    if member.id == ctx.author.id:
        await ctx.send(f"{ctx.author.mention}, YOU HAVE BEEN STOPPED BY ME YAY, you can't mute yourself!")
        return

    if discord.Member == None:
      await ctx.send(f"{ctx.author.mention}, HEY you nugget, you need to specify who you want to mute!")
      return    

    role = discord.utils.get(ctx.guild.roles, name='muted')

    if role in ctx.guild.roles:
        await member.add_roles(role)
        embed=discord.Embed(title="Muted", description=f"Offender: {member.mention} has been muted until further notice!", color=0x00FFFF)
        embed.add_field(name="Reason", value=f'{reason}', inline=True)
        embed.add_field(name="Moderator", value=f'{ctx.author.name}', inline=True)
        await ctx.send(embed=embed)
    else:
      await ctx.send(f"{ctx.author.mention}, Make sure your muted role is called `muted` in all lowercase! Then try again.")

你的想法是对的，但你需要用不同的方式来处理。

看一下下面的代码：

@bot.command()
@commands.has_permissions(manage_roles=True)
async def mute(ctx, member: discord.Member, reason=None):
    if member is None: # If no member argument was given
        await ctx.send("Please specify a member")
    else:
        # Do what you want if the member was given

• 我们只使用if和else语句。
• 如果需要，您还可以使用返回等待这样bot将不再继续。
