🧮 Simple Calculator

A basic command-line calculator built in Python that performs addition, subtraction, multiplication, and division. This was one of my early mini-projects while learning Python fundamentals.

📋 About the Project

Simple Calculator is a text-based tool that takes two numbers and an operator from the user, then returns the calculated result — with built-in handling for invalid operators and division by zero.

✨ Features

• Supports all four basic operations: +, -, *, /
• Handles division by zero gracefully with an error message
• Handles invalid operator input
• Works with decimal (float) numbers

🎮 How It Works

The calculator() function:

1. Prompts the user for a first number, an operator, and a second number
2. Checks the operator and performs the matching calculation
3. Prints the result — or a friendly error message if something goes wrong

🚀 Getting Started

Prerequisites

• Python 3.x installed on your machine

Running the Calculator

1. Clone this repository

   git clone https://github.com/Aafrakhan/Simple-Calculator.git

2. Navigate to the project folder

   cd Simple-Calculator

3. Run the script

   python Simple_Calculator.py

4. Follow the prompts to enter your numbers and operator

🖥️ Sample Run

Welcome to Python Calculator
Enter first number: 2
Enter operator (+, -, *, /): -
Enter second number: 3
Result: -1.0

🛠️ Built With

• Python — functions, conditionals, and user input handling

📚 What I Learned

This project helped me practice:

• Writing reusable functions
• Using if/elif/else chains to handle multiple cases
• Type conversion with float()
• Basic error handling (division by zero, invalid input)
