Handling Multiple Iterables with zip_longest

This function uses the zip_longest function from the itertools library to handle multiple iterable objects. If one of the iterable objects is exhausted first, fillvalue is used to fill in.

        # This generator will return the longest iterable's elements
        # or fillvalue if the shorter iterable is exhausted.
        iters = iter(iterables)
