Python Coding challenge - Day 767| What is the output of the following Python Code?

 

Code Explanation:

1) from functools import reduce

Imports the reduce function from the functools module.

reduce repeatedly applies a function to items in a sequence, reducing them to a single value.

2) nums = [2, 3, 4]

Creates a list nums containing three integers: [2, 3, 4].

3) product = reduce(lambda x, y: x * y, nums)

reduce applies the function lambda x, y: x * y (multiplication) cumulatively across nums.

Steps:

First: 2 * 3 = 6

Next: 6 * 4 = 24

So product = 24.

4) nums.append(5)

Adds the number 5 to the list.

Now nums = [2, 3, 4, 5].

5) s = reduce(lambda x, y: x + y, nums, 10)

This uses reduce with an initial value 10.

lambda x, y: x + y adds values together.

Steps:

Start with 10.

10 + 2 = 12

12 + 3 = 15

15 + 4 = 19

19 + 5 = 24

So s = 24.

6) print(product, s)

Prints both results:

product = 24

s = 24

Final Output

24 24
