How can I implement the producer-consumer problem in Python?

You can use threading and a queue to implement the producer-consumer problem. Would you like a code example?

Yes, please provide a simple code example.

Here's a basic 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()

# Create threads
producer_thread = threading.Thread(target=producer)
consumer_thread = threading.Thread(target=consumer)

# Start threads
producer_thread.start()
consumer_thread.start()

# Wait for the queue to be empty
q.join()

# Stop the consumer
q.put(None)
consumer_thread.join()

What does this code do?

This code creates a producer that generates items and puts them in a queue, while a consumer retrieves and processes those items.
