I have this command:
if message.content.lower().startswith("!activate"):
    if message.author.id not in tempo:
        await Bot.send_message(message.channel, "{} used the command".format(message.author.name))
        tempo.append(message.author.id)
        await asyncio.sleep(720)
        tempo.remove(message.author.id)
    else:
        await Bot.send_message(message.channel, "wait {} hours.".format(asyncio.sleep))
I would like every time the person tried to use the command a second time, show how much time is left before they can use it again, something like: "wait 4 hours and 50 minutes."
what should I do?
