Working with Python's deque
Real Python
EDITOR BRIEF
Python's deque supports fast adding and removing items from both the left and right sides. It can be used to build queues and stacks, and its maxlen setting lets you keep only a fixed amount of history.
INSIGHTS
This is useful when you need efficient order-based data handling in Python. Try comparing deque with a list in a small queue or history-tracking example to see when it performs better.
