I\'m setting up a Discord server for me and my friends, and I\'m in need of a bot able to add 20 reactions to any message in which a certain trigger phrase was typed. I used

Answer 1

First of all, you're going to want to change your token now, if you haven't already.

You're using syntax from a version of discord.py, v0.16, that isn't supported anymore.
See the guide for migrating to v1, specifically the Models are Stateful section.
You should use Message.add_reaction rather than Bot.add_reaction.

Answer 2

You're looking at old tutorials. Client.add_reaction was moved to Message.add_reaction in discord.py 1.0

The functionality you describe could look something like:

default_emojis = [
    "\N{GRINNING FACE}",
    "\N{KEYCAP DIGIT ONE}"
]

custom_emojis = [
    "war_tank"
]

async def react(message):
    for emoji in default_emojis:
        await message.add_reaction(emoji)
    for emoji in message.guild.emojis:
        if emoji.name in custom_emojis:
            await message.add_reaction(emoji)

@bot.event
async def on_message(message):
    if message.author == bot.user:
        return
    if "react to me" in message.content.lower():
        await react(message)
