How do I use Queue for thread synchronization in Python?

You can use the queue.Queue class in Python to manage thread synchronization. It allows threads to communicate safely.

Can you show me a simple example of how to implement it?

Sure! Here's a basic example:

import threading
import queue

# Create a queue
q = queue.Queue()

# Define a worker function
def worker():
    while True:
        item = q.get()
        if item is None:
            break
        print(f'Processing {item}')
        q.task_done()

# Start a thread
thread = threading.Thread(target=worker)
thread.start()

# Add items to the queue
for item in range(5):
    q.put(item)

# Stop the worker
q.put(None)
thread.join()

What happens if I don't use a queue?

Without a queue, threads may access shared resources simultaneously, leading to race conditions and data corruption.

Are there any alternatives to using Queue for synchronization?

Yes, you can also use threading locks, events, or semaphores for synchronization, depending on your specific use case.
