An example of an AI chatbot conversation about implementing queues and stacks in Python.
How do I implement queues and stacks in Python?
You can implement queues using the collections.deque class and stacks using a list. Would you like examples?
Yes, please provide examples for both.
For a stack, you can use stack = [] and use stack.append(item) to push and stack.pop() to pop. For a queue, use from collections import deque; queue = deque() and queue.append(item) to enqueue and queue.popleft() to dequeue.
What are the main differences between stacks and queues?
Stacks follow Last In First Out (LIFO) while queues follow First In First Out (FIFO). This affects how you access elements.
