How do I implement priority queues in my project?

To implement a priority queue, you can use data structures like heaps or linked lists. Which programming language are you using?

I'm using Python. Can you show me an example?

Sure! In Python, you can use the heapq module. Here's a simple example:

import heapq

class PriorityQueue:
    def __init__(self):
        self.elements = []

    def is_empty(self):
        return not self.elements

    def put(self, item, priority):
        heapq.heappush(self.elements, (priority, item))

    def get(self):
        return heapq.heappop(self.elements)[1]

That looks great! How do I use this priority queue?

You can use it like this:

pq = PriorityQueue()
pq.put('task1', 2)
pq.put('task2', 1)

while not pq.is_empty():
    print(pq.get())  # This will print 'task2' first, then 'task1'
