What are some alternatives to Python's heapq module?

There are several alternatives to the heapq module in Python, such as the sortedcontainers library, which provides a SortedList and SortedDict that can be more efficient for certain use cases.

Can you explain how SortedList works?

Sure! SortedList maintains its elements in sorted order, allowing for efficient insertions, deletions, and lookups. It uses a balanced tree structure under the hood.

Are there any built-in alternatives in Python?

While Python's standard library doesn't have a direct alternative, you can use the bisect module for maintaining a list in sorted order, which can be useful for certain heap-like operations.

What about using priority queues from other libraries?

Yes, libraries like queue.PriorityQueue in the standard library or third-party libraries like pqueue can also be used as alternatives for priority queue implementations.
