One way would be to use create_task function:
import asyncioasync def handler_message(request): ... loop = asyncio.get_event_loop() loop.create_task(perform_message(x,y,z)) ...As per the loop documentation, starting Python 3.10, asyncio.get_event_loop() is deprecated. If you're trying to get a loop instance from a coroutine/callback, you should use asyncio.get_running_loop() instead. This method will not work if called from the main thread, in which case a new loop must be instantiated:
loop = asyncio.new_event_loop()asyncio.set_event_loop(loop)loop.create_task(perform_message(x, y, z))loop.run_forever()Furthermore, if the call is only made once throughout your program's runtime and no other loop needs to be is instantiated (unlikely), you may use:
asyncio.run(perform_message(x, y, z))This function creates an event loop and terminates it once the coroutine ends, therefore should only be used in the aforementioned scenario.
