Root Cause

Calling queue.get_nowait() on an empty asyncio.Queue.

generic

中文

在空的asyncio.Queue上调用queue.get_nowait()。

Workarounds

  1. 95% success 
    if not q.empty(): item = q.get_nowait()
  2. 100% success 
    item = await q.get()

Dead Ends

Common approaches that don't work:

  1. 90% fail

    get() is a coroutine and must be awaited; otherwise it raises a different error.

  2. 50% fail

    May lead to null pointer issues if not handled properly.
