How does the performance of the Python queue module compare to other data structures?

The Python queue module is optimized for multi-threading and provides thread-safe FIFO semantics. Compared to lists, it has better performance for enqueue and dequeue operations in multi-threaded environments.

What are the main types of queues available in Python?

Python offers several types of queues: Queue (FIFO), LifoQueue (LIFO), and PriorityQueue (ordered by priority). Each serves different use cases.

Can you give an example of when to use a PriorityQueue?

Sure! A PriorityQueue is useful in scenarios like task scheduling, where tasks need to be processed based on their priority rather than their order of arrival.

Are there any performance benchmarks available for these queue types?

Yes, there are benchmarks available that compare the performance of these queue types under different conditions. Generally, Queue is slower than lists for single-threaded use but excels in multi-threaded scenarios.
