How can I implement a queue in Python?
You can implement a queue in Python using a list or the collections.deque class. Which one would you prefer?
What's the difference between using a list and deque?
A list allows for easy access to elements but can be slow for adding/removing items from the front. Deque is optimized for fast appends and pops from both ends.
Can you show me a simple example using deque?
Sure! Here's a basic example:
from collections import deque
queue = deque()
queue.append('first')
queue.append('second')
print(queue.popleft()) # Outputs: first
