Python Coding challenge - Day 848| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Class

class Calc:

Creates a class named Calc.

A class acts as a blueprint to define objects and their behavior (methods).

2. Defining a Method

def add_even(self, n):

    return n if n % 2 == 0 else 0

Defines a method called add_even that takes one number n.

self refers to the object that will call this method.

The method uses a ternary operator:

If n is even → returns n

If n is odd → returns 0

3. Creating an Object

c = Calc()

Creates an object c of the Calc class.

This object can now call the add_even() method.

4. Initializing the Sum

s = 0

Initializes a variable s to 0.

This will store the sum of even numbers.

5. Looping from 1 to 5

for i in range(1, 6):

    s += c.add_even(i)

range(1, 6) generates numbers 1, 2, 3, 4, 5.

For each i, the method add_even(i) is called.

Only even numbers are added to s.

Step-by-step trace:

i c.add_even(i) s after addition

1 0 0

2 2 2

3 0 2

4 4 6

5 0 6

6. Printing the Result

print(s)

Prints the final accumulated sum of even numbers from 1 to 5.

Final Output

6
