What are some examples of using asyncio queues in Python?

Asyncio queues are used for managing tasks in an asynchronous environment. For example, you can use asyncio.Queue to handle tasks in a producer-consumer scenario.

Can you show me a simple code example?

Sure! Here's a basic example:

import asyncio

async def producer(queue):
    for i in range(5):
        await queue.put(i)
        print(f'Produced {i}')
        await asyncio.sleep(1)

async def consumer(queue):
    while True:
        item = await queue.get()
        print(f'Consumed {item}')
        queue.task_done()

async def main():
    queue = asyncio.Queue()
    await asyncio.gather(producer(queue), consumer(queue))

asyncio.run(main())

What does this code do?

This code creates a producer that adds items to the queue and a consumer that processes those items. The producer waits for 1 second between producing items.

How can I modify it to handle more items?

You can increase the range in the producer function. For example, change range(5) to range(10) to produce 10 items instead.
