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

Question

我有此代码：

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，await前面应该有asyncio.wait：）

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