Python Coding challenge - Day 804| What is the output of the following Python Code?

 

Code Explanation:

Import the Math Module

import math

Imports Python’s math module.

This module provides mathematical functions like sqrt() and pow().

Create a List of Numbers

nums = [9, 25, 49]

A list named nums is created.

It contains three perfect square numbers: 9, 25, and 49.

Calculate Square Roots Using List Comprehension

roots = [math.sqrt(i) for i in nums]

math.sqrt(i) computes the square root of each number in the list.

List comprehension runs sqrt() on 9, 25, and 49 and stores the results in roots.

So roots becomes: [3.0, 5.0, 7.0]

Square the First Root

sq = math.pow(roots[0], 2)

roots[0] is 3.0

This reverses the square root operation for the first element.

Print Required Values

print(roots[1], sq)

roots[1] is the second square root → 5.0

sq is 9.0

Final output:

5.0 9.0

Final Output

5.0 9.0
