How can I use the Python queue module for advanced tasks?

The Python queue module provides a way to create and manage queues for threading. What specific advanced tasks are you looking to accomplish?

I want to implement a producer-consumer model using queues.

You can use the Queue class from the queue module to implement a producer-consumer model. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import threading
import queue
import time

# Create a queue
q = queue.Queue()

# Producer function
def producer():
    for i in range(5):
        item = f'item {i}'
        q.put(item)
        print(f'Produced {item}')
        time.sleep(1)

# Consumer function
def consumer():
    while True:
        item = q.get()
        if item is None:
            break
        print(f'Consumed {item}')
        q.task_done()

# Start threads
prod_thread = threading.Thread(target=producer)
cons_thread = threading.Thread(target=consumer)

prod_thread.start()
cons_thread.start()

# Wait for the queue to be empty
q.join()
# Stop the consumer
q.put(None)
cons_thread.join()

This code creates a producer that adds items to the queue and a consumer that processes them.
