how do i mention a user using user's id in discord.py
提问by Itachi Sama
I'm trying to code a simple bot using discord.py so i started with the fun commands like just to get the hang of the api
我正在尝试使用 discord.py 编写一个简单的机器人，所以我开始使用有趣的命令，例如只是为了掌握 api
import discord
import asyncio
client = discord.Client()
@client.event
async def on_message(message):
# we do not want the bot to reply to itself
if message.author == client.user:
return
if message.content.startswith('!hug'):
await client.send_message(message.channel, "hugs {0.author.mention}".format(message))
# Greetings
if message.content.startswith('hello'):
msg = 'Hello {0.author.mention}'.format(message)
await client.send_message(message.channel, msg)
# say (id) is the best
# This is where I am lost. how to mention someone's name or id ?
if message.content.startswith('!best'):
mid = User.id('ZERO#6885').format(message)
await client.send_message(message.channel, '{mid} mentioned')

So I finally figured out how to do this after few days of trial and error hoping others would benefit from this and have less pain than I actually had.. The solution was ultimately easy..
因此，经过几天的反复试验，我终于想出了如何做到这一点，希望其他人能从中受益，并且痛苦比我实际的痛苦要少.. 解决方案最终很简单..
if message.content.startswith('!best'):
myid = '<@201909896357216256>'
await client.send_message(message.channel, ' : %s is the best ' % myid)

If you're working on commands, you're best to use discord.py's built in command functions, your hug command will become:
如果您正在处理命令，最好使用 discord.py 的内置命令函数，您的拥抱命令将变为：
import discord
from discord.ext import commands
@commands.command(pass_context=True)
async def hug(self, ctx):
await self.bot.say("hugs {}".format(ctx.message.author.mention()))
This is assuming you've done something like this at the start of your code:
这是假设您在代码开始时已经完成了这样的操作：
def __init__(self):
self.bot = discord.Client(#blah)

From a Userobject, use the attribute User.mentionto get a string that represents a mention for the user. To get a user object from their ID, you need Client.get_user_info(id). To get the a user from a username ('ZERO') and discriminator ('#6885') use the utility function discord.utils.get(iterable, **attrs). In context:
从User对象中，使用该属性User.mention获取表示用户提及的字符串。要从用户的 ID 中获取用户对象，您需要Client.get_user_info(id). 要从用户名 ('ZERO') 和鉴别器 ('#6885') 中获取用户，请使用效用函数discord.utils.get(iterable, **attrs)。在上下文中：
if message.content.startswith('!best'):
user = discord.utils.get(message.server.members, name = 'ZERO', discriminator = 6885)
# user = client.get_user_info(id) is used to get User from ID, but OP doesn't need that
await client.send_message(message.channel, user.mention + ' mentioned')

To mention an user and have their username to display (not their id), you'll need to add a !to the accepted self-answer.
要提及用户并显示他们的用户名（而不是他们的 ID），您需要!在接受的自我回答中添加一个。
await client.send_message(message, '<@!20190989635716256>, hi!')
When you only have the id and not the Member or User object, I'd recommend against using Peter G's answer where they used get()or get_user_info(id)to actually fetch the User/Member object first. These operations are very time consuming and not needed since .mentiononly return this very string.
当您只有 id 而不是 Member 或 User 对象时，我建议不要在他们使用的地方使用 Peter G 的答案，get()或者get_user_info(id)首先实际获取 User/Member 对象。这些操作非常耗时并且不需要，因为.mention只返回这个字符串。

If you just want to respond from the on_message callback, you can grab the mention string from the author like so:
如果您只想从 on_message 回调中响应，您可以像这样从作者那里获取提及字符串：
@bot.event
async def on_message(message):
# No infinite bot loops
if message.author == bot.user or message.author.bot:
return
mention = message.author.mention
response = f"hey {mention}, you're great!"
await message.channel.send(response)

While OP's issue is long resolved (and likely forgotten) -- If you're building a Discord bot in Python, it's still a bit difficult to find this information - hopefully this helps someone. If you're trying to use the @bot.command method - the following will work (in python3):
虽然 OP 的问题早已解决（并且可能被遗忘）——如果你正在用 Python 构建一个 Discord 机器人，找到这些信息仍然有点困难——希望这对某人有所帮助。如果您尝试使用 @bot.command 方法 - 以下将起作用（在 python3 中）：
@bot.command(name='ping', help='Ping the bot to text name')
async def ping(ctx):
await ctx.send('Pong ' + format(ctx.author))
print("debug: " + dir(ctx.author))
If you want to display the nicknameof the "author" (who called the command) you can use this instead":
如果你想显示“作者”（谁调用命令）的昵称，你可以使用这个代替“：
@bot.command(name='ping', help='Ping the bot to text name')
async def ping(ctx):
# await ctx.send('Pong {0}'.format(ctx.author))
await ctx.send('Pong ' + format(ctx.author.display_name))
print("debug: " + dir(ctx.author))
Another helpful tip:
You can use dir(ctx.author)to see the attributesof the ctx.authorobject.
另一个有用的提示：您可以使用dir(ctx.author)看到属性的的ctx.author对象。
