A stack in Python is a linear data structure that follows the LIFO (Last-in, First-out) principle. It is a collection of elements where the most recently added element is the first one to be removed. The stack has two primary operations: push and pop. The push operation adds an element to the top of the stack, while the pop operation removes and returns the topmost element. The stack can also be implemented using a list in Python, where the end of the list serves as the top of the stack. Stacks are widely used in various algorithms and applications, such as expression evaluation, backtracking, and managing function calls.
