Since Python 3.7 this can be easily achieved via asyncio.create_task.
import asyncio# replace with handler_message or whichever function you want to callasyncio.create_task(YOUR_ASYNC_FUNCTION(ARG1, ARG2, ETC))Do note that that the Python docs do additionally say this:
Important
Save a reference to the result of this function, to avoid a task disappearing mid-execution. The event loop only keeps weak references to tasks. A task that isn’t referenced elsewhere may get garbage collected at any time, even before it’s done. For reliable “fire-and-forget” background tasks, gather them in a collection:background_tasks = set()
task = asyncio.create_task(some_coro(param=i)) # Add task to the set. This creates a strong reference. background_tasks.add(task) # To prevent keeping references to finished tasks forever, # make each task remove its own reference from the set after # completion: task.add_done_callback(background_tasks.discard) ```
