What are some practical use cases for the heapq module in Python?

The heapq module is great for implementing priority queues, scheduling tasks, and finding the largest or smallest elements efficiently.

Can you give me an example of using heapq for a priority queue?

Sure! You can use heapq to manage a list of tasks with priorities. For example, you can push tasks with their priorities and pop the highest priority task.

What about using heapq for sorting?

Heapq can be used to sort a list by converting it into a heap and then popping elements in sorted order, which is efficient for large datasets.

Are there any performance benefits to using heapq?

Yes, heapq operations like push and pop are O(log n), making it more efficient than sorting the entire list for frequent insertions and deletions.
