Recently - I found a youtube video (highly ranked) titled "A Very Fast And Memory Efficient Alternative To Python Lists (Deque)" and it caught my attention (for the wrong reason of course). So, I thought I could demystify this misconception about deque being super-efficient than a list with this video.
Long story short - use the right data-structure for the right purpose. And, there's a good reason why the builtin python list is not a deque! Hope you'll learn something from this video.
