When should I use deque in Python?
You should use deque when you need fast appends and pops from both ends of a collection, unlike lists.
Can you give me an example of how to use deque?
Sure! You can create a deque using from collections import deque
. Then, you can append items with append()
and appendleft()
.
What are the performance benefits of using deque over a list?
Deque has O(1) time complexity for appends and pops from both ends, while lists have O(n) for pops from the front.
Are there any downsides to using deque?
One downside is that deques use more memory than lists due to their underlying data structure.
