# Python GUI Calculator 📱
A simple graphical user interface calculator implemented in Python using the Tkinter library.
## 📜 About
This project demonstrates how to create a basic calculator with a graphical user interface using Python's Tkinter library. It's an excellent example for learning GUI programming basics and implementing mathematical operations in a user-friendly way.
## ✨ Features
- Basic arithmetic operations (addition, subtraction, multiplication, division)
- Percentage calculations
- Clear functionality
- Error handling for invalid expressions
- User-friendly interface
- Responsive design
## 🚀 Quick Start
### Installation
1. Clone the repository:
```bash
git clone https://github.com/fahadelahikhan/Python-GUI-Calculator.git
cd Python-GUI-Calculator
```
2. Run the calculator:
```bash
python Basic_Calculator.py
```
### Basic Usage
```python
# The calculator provides a graphical interface with buttons for numbers and operations
# Example calculation: 5 + 3 * 2
# Click the buttons in the following order:
# 5 -> + -> 3 -> * -> 2 -> =
# The result will be displayed in the entry field
```
### Example Calculation
```python
# Calculate (5 + 3) * 2 using the calculator
# Click sequence:
# 5 -> + -> 3 -> ) -> * -> 2 -> =
# Result: 16
```
## 📖 Documentation
### How It Works
The calculator works by:
1. Capturing user input through button clicks
2. Building an expression string
3. Evaluating the expression using Python's `eval()` function with safety checks
4. Displaying the result or error message
The mathematical operations follow standard order of operations:
```
Parentheses -> Exponents -> Multiplication/Division -> Addition/Subtraction
```
