What are some examples of queues in Python applications?

Queues are data structures that follow the First In First Out (FIFO) principle. In Python, you can use the queue module to implement queues. Some examples include task scheduling, managing requests in web servers, and handling asynchronous data streams.

Can you give me a code example of a queue in a Python application?

Sure! Here's a simple example using the queue module:

import queue

# Create a FIFO queue
q = queue.Queue()

# Add items to the queue
q.put('Task 1')
q.put('Task 2')

# Process items in the queue
while not q.empty():
    task = q.get()
    print(f'Processing {task}')

What are the differences between a queue and a stack?

A queue follows the FIFO principle, meaning the first item added is the first to be removed. A stack follows the Last In First Out (LIFO) principle, where the last item added is the first to be removed.

Are there any built-in libraries for implementing queues?

Yes, Python has a built-in queue module that provides various types of queues, including FIFO queues, LIFO queues, and priority queues.
