Welcome to an exciting exploration of two fundamental data structures: Stacks and Queues! Remember, data structures store and organize data in a manner that is structured and efficient. Stacks and Queues are akin to stacking plates and standing in a line, respectively. Intriguing, isn't it? Let's dive in!

A Stack adheres to the "Last In, First Out" or LIFO principle. It's like a pile of plates where the last plate added is the first one to be removed. Python uses the list to create a stack, with append() used for push, and pop() used for pop.

Let's explore this using a pile of plates.

The last plate added was removed first, demonstrating the LIFO property of a stack.

A Queue represents the "First In, First Out" or FIFO principle, much like waiting in line at the grocery store. Python's deque class creates queues according to the FIFO principle, providing for and for .
