How to do two tasks at the same time in asyncio or multithreading?

Question

I'm trying to achieve a task that requires real-time interaction, for example: A message (response) is received - it needs to be acted on at the same time.

I tried the multi-threading module but couldn't really get to work, so I'm demonstrating an idea here as to what I'm intending to accomplish.

Here, a message "Hello" and "How are you?" needs to be outputted at the same time as it would in 2 separate threads.

This doesn't execute "Hi, how are you?" and just keeps outputting "Hello".

import asyncio
from time import sleep

async def respond():
    while True:
        sleep(1)
        print("Hi, how are you?")

async def main():
    asyncio.create_task(respond())
    while True:
        sleep(1)
        print("Hello")

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

Yes, I need something like two threads because while one has a "loop" which is actively checking for a message - I want to create a task in another thread which will then send message to that loop to do the rest.

try to use python-worker (link)

import asyncio
from time import sleep
from worker import async_worker

@async_worker
async def respond():
    while True:
        sleep(1)
        print("Hi, how are you?")

@async_worker
async def main():
    await respond()
    while True:
        sleep(1)
        print("Hello")

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
