In Python, list slicing is a technique that extracts a portion of a list using start and end indices, while deque, a data structure from the `collections` module, allows efficient manipulation of elements from both ends.
In the reel, I demonstrated solving a list rotation problem using these methods. By list slicing, he rearranges list segments for rotation, and with deque, he rotates the list by shifting elements efficiently.
This showcases Python’s versatility in list manipulation.
