How to implement priority queue in python

sure! a priority queue is a data structure that stores elements along with their associated priority levels. the elements are retrieved based on their priority, with higher priority elements being dequeued first. in python, you can implement a priority queue using the `heapq` module, which provides heap queue algorithm implementations.

here is a step-by-step tutorial on how to implement a priority queue in python using the `heapq` module:

1. import the `heapq` module:

2. initialize an empty list to store the elements and their priorities:

3. define functions to perform operations on the priority queue:
- to push an element with its priority into the priority queue:


- to pop and return the element with the highest priority:


4. test the priority queue implementation:

in this example, we push three tasks with different priorities into the priority queue and then pop them based on their priorities. the element with the highest priority is dequeued first.

this is a simple implementation of a priority queue using the `heapq` module in python. you can further extend this implementation by adding additional functionalities or customizing it based on your specific requirements.
