Python Coding Challenge - Question with Answer (01121125)

 Explanation:

1. Defining the Class

class Test:

This line defines a class named Test.

A class in Python is a blueprint for creating objects (instances).

2. Defining a Method Inside the Class

def square(self, n):

    return n * n

This defines a method named square inside the class Test.

self refers to the object that will call this method.

n is a parameter (the number whose square we will calculate).

return n * n computes the square of n and returns it.

3. Creating an Object of the Class

t = Test()

Here, an object t is created from the class Test.

Now, t can access all the methods of the class, including square().

4. For Loop Iteration

for i in range(1, 4):

The range(1, 4) generates the sequence 1, 2, 3.

So the loop will run 3 times with i = 1, then 2, then 3.

5. Calling the Method Inside the Loop

print(t.square(i), end=" ")

On each loop iteration, the method square() is called with the current value of i.

The method returns the square of i.

The print(..., end=" ") prints each result on the same line separated by spaces.

Let’s see what happens in each iteration:

Iteration Value of i t.square(i) Printed Output

1 1 1×1 = 1 1

2 2 2×2 = 4 1 4

3 3 3×3 = 9 1 4 9

Final Output

1 4 9
