Can `asyncio.Queue` be safely created outside of the event loop thread?

[bmitc]

If anyone is interested, here’s a more fully featured prototype using asyncio.Queues heavily to communicate between asyncio workers and also as a way for a PySide6 (Qt for Python) GUI to send messages to the asyncio workers.

Request for review of PySide6 (Qt for Python) and `asyncio` task prototype

I have developed a prototype that has a PySide6 (Qt for Python) GUI running in the main thread. In a secondary thread, an asyncio event loop is running several tasks that are orchestrated via the AsyncController class, which implements the standard OOP state pattern. The GUI talks to the AsyncController via an asyncio.Queue by putting items on the queue via asyncio.run_coroutine_threadsafe. The AsyncController communicates back to the GUI using Qt’s Signal mechanism. Then I have a small worker/a…
