expression evaluation using stack in python

Title: Expression Evaluation Using Stack in Python
Introduction:
Expression evaluation is a common task in computer science and programming. In this tutorial, we will explore how to evaluate mathematical expressions using a stack data structure in Python. The stack will help us keep track of operands and operators, ensuring that the expression is processed in the correct order.
We'll start by implementing a simple stack data structure. We can use Python's built-in list as a stack.
Now, let's implement the expression evaluation algorithm using the stack. We'll support basic arithmetic operations: addition (+), subtraction (-), multiplication (*), and division (/).
This tutorial demonstrates a simple approach to evaluate mathematical expressions using a stack in Python. You can extend this implementation to handle more complex expressions or support additional operators as needed. Understanding and implementing expression evaluation is a fundamental skill in computer science and programming.
