How do I make my discord.py bot use custom emoji?

Question

How can I make my bot use my custom emoji in any discord server?

@bot.command(pass_context=True)
async def ping(ctx):
    msg = "Pong :CustomEmoji: {0.author.mention}".format(ctx.message)
    await bot.say(msg)

Example: If I upload some custom emojis on Server 1 and when we use the !ping command (mentioned above) in Server 2 or Server 3 or any server where the bot has access to, it should use the custom emoji.

Result: Pong with:CustomEmoji:

Answer 1

From https://github.com/Rapptz/discord.py/issues/390 :

It's <:emoji_name:emoji_id> for custom emojis.

You can also find the discord.Emoji instance through Server.emojis and then cast it to str.

Answer 2

同样对于动画的你做<a:emoji_name:emoji_id>

Answer 3

As we know, every discord bot has nitro privileges when it comes to using emotes. So a bot can access any emoji for all servers it has been added to. What I do is make an API converter for myself with a global emote dictionary.

emojis=None

@bot.command(pass_context=True)
async def ping(ctx):
    global emojis
    if not emojis:
        emojis = {e.name:str(e) for e in ctx.bot.emojis}
    msg = "Pong :CustomEmoji: {0.author.mention}".format(ctx.message).replace(':CustomEmoji:',emojis['CustomEmoji'])
    await ctx.send(msg)

Answer 4

@bot.event
async def on_reaction_add(reaction, user):

    if reaction.emoji.id == emoji_id:
        await reaction.message.delete()

IMPORTANT: Change the emoji_id, It deletes the message
