Async Python: fire and forget method

Originally posted on dotmethod.me

The decorator method

def fire_and_forget(f):
    from functools import wraps

    @wraps(f)
    def wrapped(*args, **kwargs):
        loop = asyncio.get_event_loop()
        if callable(f):
            return loop.run_in_executor(None, f, *args, **kwargs)
        else:
            raise TypeError('Task must be a callable')
    return wrapped

An example:

Use the method above as a decorator for other methods:

@fire_and_forget
async hello_world():
  sleep(5)
  print("Successful")
