Python Implementation of zip_longest from itertools

This function uses the `zip_longest` function from the `itertools` module to merge multiple iterable objects into an iterator. If an iterable object does not have enough elements, it is filled with `fillvalue`.

def zip_longest(*args, fillvalue=0):
    from itertools import zip_longest

    def zip_longest_inner(*args, fillvalue=0):
        for i in range(max(len(a) for a in args)):
            yield tuple(a[i] if i < len(a) else fillvalue for a in args)

    return zip_longest_inner(*args, fillvalue=fillvalue)
