Python Coding challenge - Day 859| What is the output of the following Python Code?

 

Code Explanation:

1. Class Definition

class Num:

This defines a new class named Num.

Objects of this class will store a numeric value and support custom division behavior.

2. Constructor Method (__init__)

    def __init__(self, x):

        self.x = x

__init__ is the constructor that runs when an object is created.

It takes x and stores it inside the object as self.x.

So every Num object holds a number.

3. Operator Overloading (__truediv__)

    def __truediv__(self, other):

        return Num(self.x - other.x)

__truediv__ defines behavior for the division operator /.

But here division is custom, not mathematical division.

When you do n1 / n2, Python calls this method.

Instead of dividing, it subtracts the values:

→ self.x - other.x

It returns a new Num object containing the result.

4. Creating First Object

n1 = Num(10)

Creates an object n1 with x = 10.

5. Creating Second Object

n2 = Num(4)

Creates an object n2 with x = 4.

6. Performing the “Division”

print((n1 / n2).x)

Calls the overloaded division: n1 / n2.

Internally executes __truediv__:

→ 10 - 4 = 6

Returns Num(6).

.x extracts the value, so Python prints:

6

Final Output

6
