Program To Implement Stack Operations In Python.

Stack in Python

A stack is a linear data structure that stores items in a Last-In/First-Out (LIFO) or First-In/Last-Out (FILO) manner.

In stack, a new element is added at one end and an element is removed from that end only. The insert and delete operations are often called push and pop.

Implementing a stack data structure (LIFO) in Python using built-in types and classes from the standard library.

A stack is a collection of objects that supports Last In First Out (LIFO) semantics for inserts and deletes.

Unlike lists or arrays, stacks typically don’t allow for random access to the objects they contain. The insert and delete operations are also often called push and pop.

top() – Returns the top most element of the stack.
push() – Adds the element at the top of the stack.
pop() – Deletes the top most element of the stack.

Python’s built-in data structure list can be used as a stack.

Instead of push(), append() is used to add elements to the top of stack.

While pop() removes the element in LIFO order.

A useful real-world example for a stack data structure is a stack of plates.
