How can I implement advanced queue usage in Python?

How can I implement advanced queue usage in Python?

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

What are the differences between FIFO and LIFO queues?

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

Can you show me an example of a priority queue?

Sure! Here's a simple example using PriorityQueue:

from queue import PriorityQueue

pq = PriorityQueue()
pq.put((2, 'task 2'))
pq.put((1, 'task 1'))
pq.put((3, 'task 3'))

while not pq.empty():
    print(pq.get())

This will print tasks in order of their priority.

How do I handle multiple queues in a single application?

You can create multiple instances of queue classes and manage them using a dictionary or a list, depending on your needs.
