zip_longest Function Overview

This function uses the zip_longest function from the itertools module to merge multiple iterable objects. The iterator stops when the shortest iterable is exhausted, unlike zip() which stops when the longest iterable is exhausted. If the iterables are of uneven length, missing values are filled in with fillvalue.
