Project: Build a Calculator in Python

Project: Build a Calculator 🧮

In this project, you'll build your own calculator using Python! You'll start from simple input and gradually add features like operations, a menu, and error handling — just like how real programs are built step by step.

💡 What You’ll Learn

  • Using input() and print()
  • Working with variables and data types
  • Using if-elif-else statements
  • Performing arithmetic operations
  • Handling errors and validation

🧱 Steps to Build

  1. Exercise 1: Get user input
  2. Exercise 2: Add arithmetic operations
  3. Exercise 3: Add a menu using if-elif
  4. Exercise 4: Handle invalid input and errors

Each exercise will include hints and sample code. You’ll use what you’ve already learned in the course — no new concepts, just applying them creatively!
