        if command == 'search':
            await message.channel.send('<@'+str(user)+'>, you have begun searching! It will take 2 minutes.')
            searchusers.append(user)
            time.sleep(59.99)
            await message.channel.send('<@'+str(user)+'>, there is 1 minute left.')
            time.sleep(39.99)

            found = random.randint(50, 120)
            await message.channel.send('<@'+str(user)+'>, you are done searching! You found '+str(found)+' coins!')
            setcoins(user, getcoins(user)+found)
            searchusers.remove(user)

During the time.sleep() events other bot commands do not register until the sleep function has passed. For example doing a command like /help right after doing /search the bot will not respond until after one minute, when it will respond to /help and message there is 1 minute left. I have tried sticking "await" before each one of the sleep functions but it just spit out runtime warnings at me and stopped the execution (It just says you started searching and then nothing happens).

回答1:

time.sleep() stops the entire execution of the program. If you just want to delay one async response thread use asyncio.sleep

Example:

import asyncio

async def wait():
    await asyncio.sleep(5)
    print('I waited 5 seconds')
