Lesson 16 of 19
Inheritance
Extend a class while reusing its behavior.
Introduction
Inheritance lets a child class reuse or specialize a parent class. Use it when the relationship is genuinely an is-a relationship.
super() calls parent behavior without duplicating its implementation.
Key insight
Extend a class while reusing its behavior.
Example
class Animal:
def move(self):
return "moving"
class Bird(Animal):
pass
print(Bird().move())This example shows the core inheritance idea in a small, runnable program.
Real-world example
UI components and domain models sometimes share base behavior through inheritance.
