如果选项为true，如何使用消息进行响应

Question

所以，我对此很新（目前已有30分钟的经验）并试图让我的Discord机器人在使用一个命令选项时显示一条消息。但它只是不起作用。

async def cmd_warn(self, message, user_mentions, option):
    """
    Usage:
        {command_prefix}warn [ spam | racism | discrimination | inappropriate | inpersonating | arguing | rudeness | harassment ] @UserName [@UserName2 ...]

    Warn users for spam / racism / discrimination / inappropriate / inpersonating / arguing / rudeness / harassment
    """

    if not user_mentions:
        raise exceptions.CommandError("**Error:** No users listed.", expire_in=20)

    if option not in ['spam', 'racism', 'discrimination', 'inappropriate', 'inpersonating', 'arguing', 'rudeness', 'harassment']:
        raise exceptions.CommandError(
            '**Invalid reason:** Use !help warn for more info!' % option, expire_in=20
        )

    for user in user_mentions.copy():
        if user.id == self.config.owner_id:
            print("[Commands:Warn] The owner cannot be warned (Tyler rigged).")
            user_mentions.remove(user)

    old_len = len(self.blacklist)

    if option in ['spam']:
        return Response('( %s ) You were warned for spam!')
        )

from discord.ext import commands

bot = commands.Bot(command_prefix='!')

@bot.command(pass_context=True):
async def warn(ctx, option, *members: discord.Member):
    if not members:
        raise commands.CommandError('Must mention at least one user')
    if option.lower() not in ['spam', 'racism', 'discrimination', 'inappropriate',
                              'inpersonating', 'arguing', 'rudeness', 'harassment']:
        raise commands.CommandError('Invalid reason: {}'.format(option))
    for member in members:
        if member.id == config.owner_id:
            print('Owner cannot be warned') 
        else:
            await bot.say('{} you have been warned for {}'.format(member.mention, option))

这是您要完成的基本版本。请注意，CommandError位于discord.ext.commands模块中。我也在这里直接与频道互动。

我鼓励你尽可能切换到重写分支，只因为它有异步分支缺少的documentation for the commands extension。
