Run async function in the background using asyncio and multiprocessing

async_multiprocessing.py

from asyncio import sleep, get_event_loop, get_running_loop
from multiprocessing import Process


# Simple callback function
async def my_callback_func():
    print(f"Doing something in the background!")
    await sleep(1)

# Run the callback function in a loop as you need to use async / await
# Else you can just ignore this function and call your callback function directly from "fire_callback" function

    try:
        loop = get_running_loop()
    except:
        loop = get_event_loop()

# Fire the callback function
def fire_callback(callback):
    Process(target=handle_callback, args=(callback,)).start()


# Call "fire_callback" for a test run
fire_callback(my_callback_func)
