Is there a way to use asyncio.Queue in multiple threads?

Question

Let\'s assume I have the following code:

import asyncio
import threading

queue = asyncio.Queue()

def threaded():
    import time
    while True:
        ti         


        

Answer 1

BaseEventLoop.call_soon_threadsafe is at hand. See asyncio doc for detail.

Simply change your threaded() like this:

def threaded():
    import time
    while True:
        time.sleep(1)
        loop.call_soon_threadsafe(queue.put_nowait, time.time())
        loop.call_soon_threadsafe(lambda: print(queue.qsize()))

Here's a sample output:
