zip_longest Function Overview

This function uses the `zip_longest` method from the `itertools` module to combine multiple iterators, so that the length of the returned iterator is equal to the length of the longest input iterator. If an iterator ends prematurely, `fillvalue` is used to fill the remaining positions.
