Object-Oriented Programming

As programs grow, code can become harder to manage.

Using only variables, functions, and dictionaries works for small projects, but larger programs need better structure.

That is where Object-Oriented Programming (OOP) helps.

OOP organizes code using classes and objects.

What You Will Learn

• What OOP means
• What classes are
• What objects are
• How to use attributes
• How to create methods
• How __init__() works
• How to create many objects
• Encapsulation
• Inheritance
• Polymorphism
• How to build projects with OOP

Why This Module Matters

Many real Python programs use OOP.

It helps you:

• organize code
• reuse code
• build larger apps
• model real-world things
• write cleaner programs

Real Examples of OOP

You can model things like:

• Students
• Bank accounts
• Cars
• Products
• Users
• Games

Practical Focus

You will build beginner-friendly examples such as:

• Student class
• Bank account system
• Product inventory
• Car objects
• OOP mini apps

Success Goal

By the end of this module, you will understand classes and objects and be able to build organized Python programs using OOP.
