Abstraction in Python

Abstraction in Python involves hiding the complex implementation details of a class
and showing only the necessary features of an object. It allows programmers to
focus on the essential aspects of an object while hiding the irrelevant details. The
following is an example of defining the syntax for abstraction.

from abc import ABC, abstractmethod
class MyAbstractClass(ABC):
#abstractmethod
def my_abstract_method(self):
pass

The following Program Example 6.6 demonstrates abstraction in Python.
Program Example 6.6:

Program codes to demonstrate abstraction

from abc import ABC, abstractmethod
# Abstract class
class Animal(ABC):
@abstractmethod
def make_sound(self):
pass
# Concrete classes
class Dog(Animal):
