Fraction Class using OOP in Python

A Python project that demonstrates Object-Oriented Programming (OOP) by creating a custom Fraction class. The project uses operator overloading to perform arithmetic operations on fractions just like built-in numeric types.

Features

• Create fraction objects
• Addition of fractions
• Subtraction of fractions
• Multiplication of fractions
• Division of fractions
• Operator overloading using Python magic methods
• Clean and readable OOP implementation

Concepts Used

• Python Classes & Objects
• Constructors (__init__)
• Magic Methods
  • __str__
  • __add__
  • __sub__
  • __mul__
  • __truediv__
• Object-Oriented Programming (OOP)

Project Structure

fraction.py
README.md

Example

a = Fraction(5, 4)
b = Fraction(4, 3)

print(a + b)
print(a - b)
print(a * b)
print(a / b)

Output

5/4 + 4/3 = 31/12
5/4 - 4/3 = -1/12
5/4 * 4/3 = 20/12
5/4 / 4/3 = 15/16

Learning Outcomes

This project helped me understand:

• How classes and objects work in Python
• Operator overloading using magic methods
• Creating custom data types
• Implementing arithmetic operations with OOP

Future Improvements

• Simplify fractions automatically
• Validate denominator (prevent zero division)
• Compare fractions using comparison operators
• Convert fractions to decimal values
