Welcome to the advanced Python Object-Oriented Programming tutorial! This guide dives into sophisticated topics to elevate your understanding of OOP in Python. Let's explore key concepts together.

Core Principles of Advanced OOP

  1. Inheritance & Polymorphism

    • Extend classes with class inheritance
    • Override methods for dynamic behavior
    • Use super() for method resolution

  2. Encapsulation

    • Hide internal state with private attributes (_variable)
    • Control access via getters and setters
    • Maintain data integrity through validation
    encapsulation

  3. Abstraction

    • Simplify complex systems with abstract classes
    • Use abc module for interface definition
    • Focus on essential features while hiding complexity
    abstraction

Advanced Features to Master

  • Multiple Inheritance 

    class A: ...
class B: ...
class C(A, B): ...

  • Metaclasses

    • Customize class creation with type or custom metaclasses
    • Useful for ORM frameworks or API generators
    metaclasses

  • Slots

    • Optimize memory usage with __slots__
    • Restrict attribute access for performance
    slots

Practical Example: Design Patterns

Let's implement a Strategy Pattern: 

class Strategy:
    def execute(self):
        pass

class ConcreteStrategy(Strategy):
    def execute(self):
        print("Executing specific strategy logic")

# Usage
strategy = ConcreteStrategy()
strategy.execute()

  • Experiment with __mro__ and method resolution order
  • Practice creating your own metaclasses and decorators
