Python Coding challenge - Day 839| What is the output of the following Python Code?

 Code Explanation:

1) Define the class

class Square:

This starts the definition of a class named Square.

It will represent a square with side length s.

2) Constructor method (__init__)

    def __init__(self, s):

        self.s = s

__init__ runs whenever a new Square object is created.

It takes s (the side length) and stores it in the instance variable self.s.

3) Create a computed property

    @property

    def diag(self):

        return (2 * (self.s**2)) ** 0.5

@property

This decorator makes diag behave like an attribute instead of a method.

So we can use Square(4).diag instead of Square(4).diag().

diag calculation

A square’s diagonal formula is:

(2 * (self.s**2)) ** 0.5

self.s**2 → square of the side

Multiply by 2 → gives 2s²

Raise to power 0.5 → square root

4) Create an object and print diagonal

print(int(Square(4).diag))

Square(4) creates a square with side = 4.

.diag fetches its diagonal value:

2×16=32 ≈5.656

int(...) converts it to an integer → 5.

print() outputs the value.

Final Output

5
