How does the performance of Python's deque compare to lists?

How does the performance of Python's deque compare to lists?

Python's deque is optimized for fast appends and pops from both ends, while lists are slower for these operations.

Can you give me an example of when to use deque over a list?

Use deque when you need to efficiently add or remove items from both ends, like in a queue or stack implementation.

What are the time complexities for deque operations?

Deque operations like append and pop from either end are O(1), while list operations can be O(n) for certain cases.

Are there any downsides to using deque?

Yes, deques use more memory than lists and may have slightly slower access times for random elements.
