Inheritance in Python

Inheritance is the process by which a new class (subclass or derived class) is created
from an existing class (superclass or base class).

Syntax: In Python, inheritance is declared by mentioning the superclass name
in parentheses after the subclass name. Subclasses have the ability to override
superclass methods, allowing them to provide their own implementations or
enhance the functionality of inherited methods. The following Program Example
6.5 demonstrate inheritance in Python.

Program Example 6.5:
Program codes demonstrating inheritance

class Animal:
def speak(self):
print(“Animal speaks”)
# Dog class inherits from Animal class

class Dog(Animal):
def bark(self):
print(“Dog barks”)
# Creating an object of the Dog class
