Either of those options sounds fine to me. Instead of creating your coroutine object at the very beginning, create your coroutine *function*. Wait until you know you're going to do your second operation, and create your coroutine object then! --Chris > > My async_poller object being something like: > > class PollerOperation: > async def result(self): > ...async version of previous sync result()... > > So the questions are: > - Does this seem a correct pattern? > - Is there a simple way to achieve something like this: > > obj = await async_poller > > meaning, I can win the "result()" syntax and directly "await" on the object > and get the result from magic function.
