Aggregating Elements from Iterables with Fillvalue

The function is used to aggregate elements from multiple iterable objects. If the length of the iterables is different, fillvalue is used to fill in missing values.

def zip_longest(*iterables, fillvalue=None):
    "Make an iterator that aggregates elements from each of the iterables.
    The iterables must be of the same length or the shortest iterable is used.
    Fillvalue is used for missing values if the iterables are of different lengths."

    return zip_longest_from_itertools(*iterables, fillvalue=fillvalue)
