Question

Python

What to do bot sends two or three identical messages instead of one. What to do?
import discord

client = discord.Client()

@client.event
async def on_ready():
    print('We have logged in as {0.user}'.format(client))

@client.event
async def on_message(message):
    message.content = message.content.lower()
    if message.author == client.user:
        return

    if message.content == ('ghbdtn' or 'ghbdtn!' or 'ghbdtn)'):
        await message.channel.send(f'>>> **_{message.author}_  хотел сказать:**  Привет!')
        await message.delete()
    if message.content == ('gjrf' or 'gjrf!' or 'gjrf)'):
        await message.channel.send(f'>>> **_{message.author}_  хотел сказать:**  Пока!')
        await message.delete()
    if message.content == ('cgc' or 'cgc!' or 'cgc)' or 'cgfcb,j' or 'cgfcb,j!' or 'cgfcb,j)'):
        await message.channel.send(f'>>> **_{message.author}_  хотел сказать:**  Спасибо!')
        await message.delete()
    if message.content == ('rfr ltkf' or 'rfr ltkf?' or 'rfr ltkf)' or 'rfr ltkf,' or 'rfr ltkbirb'):
        await message.channel.send(f'>>> **_{message.author}_  хотел сказать:**  Как дела?')
        await message.delete()

client.run('token')

And such error gets out.

Answer 1

A record of the form: indicates a complete ignorance of the Python language. Accordingly, without knowing the language, nothing good can be written. Great happiness that this code at least does not control nuclear warheads. You have to start with the basics.
if xxx == ('a' or 'b' or 'c'):

message_content in ("first_string", "second_string")
