Summary Python theory

Polymorphism Polymorphism is the ability of objects of different classes to be treated as if they were objects of a common superclass. This allows you to write more flexible and reusable code by defining common interfaces and implementing them in different classes. Here's an example to illustrate polymorphism in Python: from abc import ABC, abstractmethod class Shape(ABC): @abstractmethod def area(self): pass class Rectangle(Shape): def __init__(self, width, height): = width t = height def area(self): return * t class Circle(Shape): def __init__(self, radius): s = radius def area(self): import math return * (s ** 2) shapes = [Rectangle(4, 5), Circle(3)] for shape in shapes: print(()) In this example, we've defined an abstract Shape class with an abstract area method. We've then created two subclasses (Rectangle and Circle) that implement the area method in their own way. By doing this, we can treat both Rectangle and Circle objects as if they were Shape objects and call the area method on them, without needing to know the specific implementation details of each class. These are just a few of the key OOP concepts covered in the video. I hope this summary has been helpful in conveying the main ideas and providing some practical examples. Happy coding!
