Quiz: Python Stacks, Queues, and Priority Queues in Practice

In this quiz, you’ll test your understanding of Python stacks, queues, and priority queues.

You’ll review LIFO and FIFO behavior, enqueue and dequeue operations, and how deques work. You’ll implement a queue with collections.deque and learn how priority queues order elements.

You’ll also see how queues support breadth-first traversal, stacks enable depth-first traversal, and how message queues help decouple services in real-world systems.
