#Deque
A deque (double-ended queue), from collections library, has the feature of adding and removing elements from either end(source). It is preferred over list in the cases where we need quicker append and pop operations from both the ends of container, as deque provides an O(1) time complexity for append and pop operations as compared to list which provides O(n) time complexity (source).

deque(maxlen=N) creates a fixed-sized queue. When new items are added and the queue is full, the oldest item is automatically removed. (Source: "Python Cookbook")
