Code Explanation:

Importing the Operator Module

import operator

This imports Python’s built-in operator module, which contains function versions of basic arithmetic operations like add, mul, pow, truediv, etc.

Instead of using symbols like +, *, /, you can use these function forms — for example, operator.add(2,3) does the same as 2 + 3.

Creating a List of Numbers

nums = [5, 10, 15, 20]

This creates a list named nums containing four integers:

[5, 10, 15, 20]

You’ll use these numbers in various arithmetic operations below.

Multiplying the First Two Numbers

mul1 = operator.mul(nums[0], nums[1])

nums[0] is 5

nums[1] is 10

operator.mul(5, 10) multiplies them.

So mul1 = 50.

Adding the Third Number

add1 = operator.add(mul1, nums[2])

mul1 is 50

nums[2] is 15

operator.add(50, 15) adds them together.

So add1 = 65.

Dividing the Sum by 5

div1 = operator.truediv(add1, 5)

add1 is 65

Divide by 5 → operator.truediv(65, 5) = 13.0

So div1 = 13.0.

Squaring the Integer Part

final = operator.pow(int(div1), 2)

int(div1) converts 13.0 to 13

operator.pow(13, 2) means 

So final = 169.

Adding the Last Element of the List

print(final + nums[-1])

nums[-1] means the last element of the list, which is 20

Adds final + 20 → 169 + 20 = 189

So the final value printed is 189.

Output

189
