Discord.py - 如何（在）从 Bot 命令中提及 Discord 用户 [重复]

Question

真的不是骗子吗？说明：
This question is not looking to (at)mention a user
This question lists member.mention but does not provide a complete example

我的问题
使用 Discord.py（如果标题不够清晰），我试图弄清楚如何在 Discord 用户运行命令时向他们添加 @mention 属性。

示例：
用户输入：$99
机器人输出：@User 你的报价是：Bingpot！

更新：2019 年 10 月 24 日
- @epic-programmer 指出了一个非常严重的复制粘贴错误，我已修复 :)
- 该修复将“成员”设置为命令的参数。我想要的是获取成员显示名称，并在命令输出中使用它（作为@提及）

谷歌答案

@commands.command()
async def mention_ping(self, ctx, member : discord.Member):
    await ctx.send(f"PONG {member}")

我的代码（更新：使用@epic-programmers 部分修复）

import random
import discord

from discord.ext import commands

#----
tokenfile = 'token.txt'
with open(tokenfile) as tf:
    line = tf.readline()
    TOKEN = line.rstrip()
#----

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

@bot.command(name='99', help='Responds with a random quote from Brooklyn 99')
async def nine_nine(ctx, member : discord.Member):
    brooklyn_99_quotes = [
        'I\'m the human form of the ???? emoji.',
        'Bingpot!',
        (
            'Cool. Cool cool cool cool cool cool cool, '
            'no doubt no doubt no doubt no doubt.'
        ),
    ]

    response = random.choice(brooklyn_99_quotes)
    await ctx.send("{} your quote is: {}".format(member, response))

bot.run( TOKEN)

member 参数位于错误的位置。尝试将其移至 def 语句。

@bot.command(name='99', help='Responds with a random quote from Brooklyn 99')
async def nine_nine(ctx, member : discord.Member):
    brooklyn_99_quotes = [
        'I\'m the human form of the ? emoji.',
        'Bingpot!',
        (
            'Cool. Cool cool cool cool cool cool cool, '
            'no doubt no doubt no doubt no doubt.'
        ),
    ]

    response = random.choice(brooklyn_99_quotes)
    await ctx.send("{} your quote is: {}".format(member, response))

bot.run( TOKEN)

编辑：为了提及当前用户调用命令，您可以这样做：

from typing import Optional

@bot.command(name='99', help='Responds with a random quote from Brooklyn 99')
async def nine_nine(ctx, member : Optional[discord.Member] = None):
    member = member or ctx.author
    brooklyn_99_quotes = [
        'I\'m the human form of the ? emoji.',
        'Bingpot!',
        (
            'Cool. Cool cool cool cool cool cool cool, '
            'no doubt no doubt no doubt no doubt.'
        ),
    ]

    response = random.choice(brooklyn_99_quotes)
    await ctx.send("{} your quote is: {}".format(member, response))

bot.run( TOKEN)

此代码块将检查 ping，如果找不到，则默认为调用该命令的用户。
