[FIXED] should python asyncio task always return something?

Issue

It may sound like a dumb questions but I could not find a clear answer .

I can read, in the asyncio doc here:

done() Return True if the Task is done.

A Task is done when the wrapped coroutine either returned a value, raised an exception, or the Task was cancelled.

does this mean that whatever coroutine I created , It must always return something and not simply end when the job is done ?? If yes , what is the most pythonic way to do it ? return 0 or return None ?

Solution

All python functions return None upon completion if not explicitly provided a return value so you don't need to explicitly return anything. If you need to return early you can use just return without any value which is equivalent to return None.
