asyncio.await失败，并出现TypeError：无法解包不可迭代的协程对象

Question

我有以下代码：

done, pending = asyncio.wait(

    [a, b],

    return_when=asyncio.FIRST_COMPLETED)

但是失败了：

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

好吧，应该await在asyncio.wait:)前面done, pending = await asyncio.wait(    [a, b],    return_when=asyncio.FIRST_COMPLETED)
