Python Coding challenge - Day 546| What is the output of the following Python Code?

 

Code Explanation:

1. Importing operator Module

import operator

The operator module contains many useful functions that correspond to standard operators.

For example, operator.mul represents the multiplication operator (*).

2. Importing reduce Function from functools

from functools import reduce

reduce() is a function that applies a binary function (a function taking two arguments) cumulatively to the items of a sequence.

It's part of the functools module.

3. Defining a List of Numbers

nums = [1, 2, 3, 0, 4]

A list named nums is defined with 5 integers: 1, 2, 3, 0, 4.

4. Applying reduce() with operator.mul

result = reduce(operator.mul, nums)

reduce(operator.mul, nums) will multiply the elements of nums from left to right:

((((1 * 2) * 3) * 0) * 4)

Intermediate steps:

1 × 2 = 2

2 × 3 = 6

6 × 0 = 0

0 × 4 = 0

Final result is 0, because anything multiplied by 0 becomes 0.

5. Printing the Result

print(result)

This line prints the final result of the multiplication, which is:

0

Final Output:

0
