Python Coding challenge - Day 531| What is the output of the following Python Code?

 

Code Explanation:

1. Importing reduce from functools

from functools import reduce

reduce() is used to apply a function cumulatively to the items of a sequence (like a loop that combines all values into one).

2. Importing operator Module

import operator

The operator module contains standard operators as functions.

We'll use operator.mul, which is the multiplication operator * as a function.

3. Defining the List

nums = [1, 2, 3, 4]

A list of integers we want to process.

4. Calculating the Total Product of All Elements

total_product = reduce(operator.mul, nums)

reduce(operator.mul, nums) computes:

1 * 2 * 3 * 4 = 24

So, total_product = 24

5. Creating a Result List

python

Copy

Edit

result = [total_product // n for n in nums]

This is a list comprehension.

For each n in nums, it computes 24 // n.

So:

24 // 1 = 24

24 // 2 = 12

24 // 3 = 8

24 // 4 = 6

Final list: [24, 12, 8, 6]

6. Printing the Result

print(result)

Output:

[24, 12, 8, 6]

Final Output:

[24, 12, 8, 6]
