How can I implement advanced queue operations in Python?

How can I implement advanced queue operations in Python?

You can use the queue module in Python, which provides a FIFO implementation. For advanced operations, consider using PriorityQueue or deque from the collections module.

What are the differences between FIFO and LIFO queues?

FIFO (First In, First Out) queues process items in the order they were added, while LIFO (Last In, First Out) stacks process the most recently added items first.

Can you show me an example of a priority queue?

Sure! Here's a simple example using PriorityQueue:

import queue
pq = queue.PriorityQueue()
pq.put((2, 'task 2'))
pq.put((1, 'task 1'))
while not pq.empty():
    print(pq.get())

This will output tasks in order of their priority.

How do I handle exceptions in queue operations?

You can use try-except blocks to handle exceptions. For example, when trying to get an item from an empty queue, you can catch the queue.Empty exception.
