What is Data Abstraction in Python?

The hiding of implementation details of the process and showing required information to the user is called Data Abstraction.

Example:: 

Take example of below output::

Enter two numbers:: 13 12 The sum is 25

In the above output we are asking users two numbers and showing the sum. But we are not showing how addition is done internally. This is called Abstraction.

Actually the two inputs taken from the user are converted into int data type and stored in two different variables. Then they are converted into binary form and then perform their binary addition and then convert binary sum to decimal number sum and store it in a variable. This is what actually done by the program. But it is showing sum of two numbers which is required to the user. This is called Abstraction.

Once see the output if there is no Abstraction implemented by Python

Enter two numbers:: 13 12 Performing addition operation using the binary representation of the numbers... Binary representation of 13:: 1101 Binary representation of 12:: 110 Adding binary numbers... 1 1 0 1 1 1 0 0 ------------- 1 1 0 0 1 ------------- Conversion to decimal... Binary number 11001 is equivalent to decimal number 25 The sum of 13 and 12 is 25

Crazy right ! 😄

Here in the above examples I explained inbuilt python Abstraction. Actually there is no term inbuilt Abstraction, just for explanation I have added it.

Like how python gives 5 as output if we type 2 + 3 in python interpreter, likewise our programs also should be written by giving only required information and Hiding complexities. NOW Let us come to the real implementation of data Abstraction in python.

It is done through Abstract method.

from abc import ABC, abstractmethod class Animal(ABC): @abstractmethod def sound(self): pass class Dog(Animal): def sound(self): print("Dog says bark") class Cat(Animal): def sound(self): print("Cat says meow") class Goat(Animal): def sound(self): print("Goat says mey may") # Create instances of the classes dog = Dog() cat = Cat() goat = Goat() # Make the animals sound dog.sound() cat.sound() goat.sound()
