Discord py自动反应问题

Question

I have an event in my discord.py bot that is supposed to only react with an emoji to a message containing "welc" or "welcome", however, the bot reacts to all messages sent in the chat. Heres the code for the event.

    @commands.Cog.listener()
    async def on_message(self, message):
        welcome1 = 'welcome'
        welc = 'welc'
        if message.content == welcome1 or welc:
            await message.add_reaction('<:z_heart1:786021804690636810>')

I have tried using an else pass in my if statement but that doesn't seem to work.

Answer 1

The reason is, if message.content == welcome1 or welc: and if message.content == welcome1 or message.content == welc: are not the same. You can use if message.content in [welcome1, welc] .

    welcome1 = 'welcome'
    welc = 'welc'
    @commands.Cog.listener()
    async def on_message(self, message):
        if message.content in [welcome1, welc]:
            await message.add_reaction('<:z_heart1:786021804690636810>')

Answer 2

if message.content == welcome1 or welc: is where it's breaking. or welc which means if welc is not None and welc is not False. In this case welc has the value of welc

You can use a list like in my example to reduce the need for or statements.

    @commands.Cog.listener()
    async def on_message(self, message):
        welcome1 = 'welcome'
        welc = 'welc'
        if message.content in [welcome1,welc]:
            await message.add_reaction('<:z_heart1:786021804690636810>')
