Python Coding challenge - Day 381| What is the output of the following Python Code?

Code Explanation:

Importing Required Modules

from abc import ABC, abstractmethod  

ABC (Abstract Base Class) is imported from the abc module.

@abstractmethod is used to define an abstract method.

Defining an Abstract Class (P)

class P(ABC):  

    @abstractmethod  

    def calc(self, x):  

        pass  

P is an abstract class because it inherits from ABC.

calc(self, x) is an abstract method (it has no implementation).

Any subclass of P must override calc() before being instantiated.

Creating a Subclass (Q)

class Q(P):  

    def calc(self, x):  

        return x * 2  

Q inherits from P and provides an implementation for calc().

Since calc() is now implemented, Q is no longer abstract and can be instantiated.

Instantiating Q and Calling calc()

print(Q().calc(5))  

An object of Q is created: Q().

The calc(5) method is called, which returns 5 * 2 = 10.

Final Output

10
