How can I implement a priority queue in Python using the queue library?

You can use the PriorityQueue class from the queue module. It allows you to manage items with priorities.

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

Sure! Here's a basic example:

import queue

pq = queue.PriorityQueue()

# Adding items with priorities
pq.put((2, 'task 2'))
pq.put((1, 'task 1'))
pq.put((3, 'task 3'))

# Retrieving items in priority order
while not pq.empty():
    print(pq.get())

What happens if two tasks have the same priority?

If two tasks have the same priority, they are retrieved in the order they were added, following FIFO (First In, First Out).
