Python Coding challenge - Day 545| What is the output of the following Python Code?

 

Code Explanation:

1. Import Required Modules

from functools import reduce

import operator

reduce: Applies a function cumulatively to the items in a list.

operator.mul: Built-in multiplication function (like using *).

2. Define the List of Numbers

nums = [1, 2, 3, 4]

The input list whose product variants are to be calculated.

3. Calculate the Total Product of All Elements

total_product = reduce(operator.mul, nums)

Computes: 1 * 2 * 3 * 4 = 24

total_product will be 24.

4. Build the Result List

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

For each element n in nums, divide total_product by n.

This gives the product of all elements except the current one.

Example:

[24 // 1, 24 // 2, 24 // 3, 24 // 4] → [24, 12, 8, 6]

5. Print the Result

print(result)

Final output will be:

[24, 12, 8, 6]
