Python Coding challenge - Day 884| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition: class X

class X:

Defines a new class named X.

This class will act as a base/parent class.

2. Method in Class X

def val(self):

    return 3

Creates a method called val.

When called, it simply returns 3.

No parameters except self.

3. Class Definition: class Y(X)

class Y(X):

Defines class Y.

Y(X) means Y inherits from X.

So Y can access methods from X.

4. Overriding Method in Class Y

def val(self):

    return super().val() * 2

Y overrides the val() method from X.

super().val() calls the parent class (X) version of the method.

Parent method returns 3.

Then Y multiplies it by 2 → 3 * 2 = 6.

5. Creating Object of Class Y

y = Y()

Creates an object y of class Y.

6. Printing the Result

print(y.val())

Calls Y’s overridden val() method.

Computation: super().val() * 2 → 3 * 2 = 6

Output: 6

Final Output

6
