I want to trigger the discord bot on a specific word in python but can’t find the right way

Solution for I want to trigger the discord bot on a specific word in python but can’t find the right way
is Given Below:

I recently made a discord bot using python for fun but I am unable to find the right way to trigger the bot when the user says a specific word like “rn” because in my code even a word that includes that word inside it like morning triggers the bot. Here’s my code:

    if "rn"in message.content.lower():
        await message.channel.send('Really Right now?')

Help would be really appreciated

There is probably a way to do this with regex, but you can do some checks that might solve your problem.
At first, I would suggest checking if there is a space before the rn due to it being used as a word (at least in the cases I can think of).

 if " rn" in message.content.lower():
    await message.channel.send('Really Right now?')

Another case I can think of is someone just saying “rn” with context to some previously posted message.
In this case, you can check whether the message consists of only “rn” due to them not starting a message with a space.

if "rn" == message.content.lower():
    await message.channel.send('Really Right now?')

To make matters a bit cleaner you can combine these two to

if ("rn" == message.content.lower() or " rn" in message.content.lower()):
    await message.channel.send('Really Right now?')
