multiprocessing classes SimpleQueue and Queue don't support typing in 3.11.0 #99509
Description
Bug report
SimpleQueue and Queue classes from multiprocessing module in Python 3.11.0 do not support type [str] annotation.
Minimal, reproducible example:
from multiprocessing import Queue
multiprocessing_queue: Queue[str] = Queue()or
from multiprocessing import SimpleQueue
multiprocessing_queue: SimpleQueue[str] = SimpleQueue()Result - error:
multiprocessing_queue: SimpleQueue[str] = SimpleQueue()
~~~~~~~~~~~^^^^^
TypeError: 'method' object is not subscriptableHow it should work:
It should work like Queue from the queue module:
from queue import Queue
standard_queue: Queue[str] = Queue()Result - no error.
Why do I need this?
I want my IDE to know that queue.get() returns str object.
