What are some advanced techniques for using heapq in Python?

You can use heapq for various advanced techniques like merging multiple sorted iterables, implementing priority queues, and more.

Can you explain how to merge multiple sorted lists using heapq?

Sure! You can use heapq.merge() to merge multiple sorted lists efficiently. It returns an iterator of the sorted values.

What about using heapq for a priority queue?

You can implement a priority queue by using a min-heap with tuples, where the first element is the priority.

Are there any performance considerations I should be aware of?

Yes, while heapq operations are efficient, be mindful of the overhead when dealing with large datasets or frequent updates.
