Inheritance

Inheritance

A child class inherits attributes and methods from a parent class. Use super() to call the parent's methods.

Basic Inheritance

class Animal:
    def __init__(self, name):
        self.name = name

    def speak(self):
        return "..."

class Dog(Animal):
    def speak(self):
        return "Woof!"

d = Dog("Rex")
print(d.name, d.speak())

Using super()

class Vehicle:
    def __init__(self, brand):
        self.brand = brand

class Car(Vehicle):
    def __init__(self, brand, model):
        super().__init__(brand)
        self.model = model

    def info(self):
        return f"{self.brand} {self.model}"

c = Car("Toyota", "Corolla")
print(c.info())

Multiple Inheritance

A class can inherit from more than one parent.

class Flyer:
    def fly(self):
        return "Flying"

class Swimmer:
    def swim(self):
        return "Swimming"

class Duck(Flyer, Swimmer):
    pass

d = Duck()
print(d.fly())
print(d.swim())
