asyncio.await fails with TypeError: cannot unpack non-iterable coroutine object

Question

I have this code:

done, pending = asyncio.wait(
    [a, b],
    return_when=asyncio.FIRST_COMPLETED)

But it fails:

Traceback (most recent call last):
  ...
  File "/.../api.py", line 83, in websockets_handler
    return_when=asyncio.FIRST_COMPLETED)
TypeError: cannot unpack non-iterable coroutine object

Answer 1

Well, there should be await in front of asyncio.wait :)

done, pending = await asyncio.wait(
    [a, b],
    return_when=asyncio.FIRST_COMPLETED)
