How can I implement an async queue in Python?

You can use the asyncio library to create an async queue. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import asyncio

async def worker(queue):
    while True:
        item = await queue.get()
        if item is None:
            break
        print(f'Processing {item}')
        await asyncio.sleep(1)  # Simulate work

async def main():
    queue = asyncio.Queue()
    # Start worker tasks
    workers = [asyncio.create_task(worker(queue)) for _ in range(3)]
    # Add items to the queue
    for item in range(10):
        await queue.put(item)
    # Stop workers
    for _ in workers:
        await queue.put(None)
    await asyncio.gather(*workers)

asyncio.run(main())

What does the None in the queue signify?

The None is used as a sentinel value to signal the workers to stop processing when there are no more items left.
