Python Object-Oriented Programming Masterclass

Learn how classes act as blueprints and how you create objects as instances from them, with examples of a car class and a dog class with a bark method.

Explore Python's __init__ method as the constructor that auto runs to initialize an object's attributes, using self to set the initial state and display details.

Create a book class with an init constructor to initialize title, author, and price as instance variables. Display details and update the price with a dedicated update method.

Explore encapsulation and the three attribute types in Python: public, protected (leading underscore), and private (double leading underscores) with examples like a person and a bank account.

Learn how property decorators enable getters and setters to safely access private attributes, exemplified by an account balance with validation and a pythonic, encapsulated design.

In this Python object-oriented programming masterclass, build a car class with private attributes speed and fuel_level, using property decorators for getters and setters with range validation.

Explore how inheritance enables one class to reuse attributes and methods from a parent class, with dog and cat examples that override speak for woof woof and meow meow.

Learn how to override parent methods in Python using super, enabling child classes to extend and combine inherited behavior with new updates.

Define a general shape class and extend it with circle and rectangular subclasses to compute area and perimeter, demonstrating inheritance and polymorphism in a Python project.

Explore how polymorphism enables a single interface to call move methods across car, bike, and track subclasses of a vehicle class, demonstrating overridden behavior.

Explore abstraction in Python with the ABC module to define abstract classes and methods, enforcing a contract for subclasses, and implement examples like a dog that defines make_sound and sleep.

Define an abstract payment processor class with an abstract process_payment method. Implement concrete credit card and PayPal payment subclasses and demonstrate a main routine that processes a sample amount.
