zip_longest Function: Aggregating Iterables with Fillvalue

The function takes multiple iterable objects and returns a zip object that aggregates elements from each iterable. If the iterables are of unequal lengths, missing values in the shorter iterables are filled with fillvalue.

    # This function takes several iterables and returns a zip object that aggregates elements from each iterable.
    # If the iterables are of unequal lengths, missing values in the shorter iterables are filled with fillvalue.

    # Using zip to combine the iterables
    # Using itertools.zip_longest to handle the filling of missing values
    from itertools import zip_longest

    # The zip object is created and returned
    return zip_longest(*iterables, fillvalue=fillvalue)
