Python Coding challenge - Day 770| What is the output of the following Python Code?

 

Code Explanation:

1. Importing itertools

import itertools

The itertools module provides tools for creating iterators for efficient looping.

We’ll use it here to generate combinations of numbers.

2. Creating a list of numbers

nums = [1, 2, 3, 4]

A simple list of integers is defined:

nums = [1, 2, 3, 4]

3. Generating all 2-element combinations

comb = list(itertools.combinations(nums, 2))

itertools.combinations(nums, 2) generates all unique pairs of elements from nums (order does not matter).

Converting to a list gives:

comb = [(1,2), (1,3), (1,4), (2,3), (2,4), (3,4)]

4. Computing sums of each pair

sums = [sum(c) for c in comb]

This is a list comprehension that calculates the sum of each pair c.

Resulting sums:

sums = [3, 4, 5, 5, 6, 7]

5. Printing statistics

print(len(comb), max(sums), min(sums))

len(comb) → number of combinations → 6.

max(sums) → largest sum → 7.

min(sums) → smallest sum → 3.

Final Output:

6 7 3
