DOCUMENTATION:
name: zip_longest
version_added: "2.3"
short_description: combine list elements, with filler
positional: _input, _additional_lists

- Make an iterator that aggregates elements from each of the iterables.
If the iterables are of uneven length, missing values are filled-in with I(fillvalue).
Iteration continues until the longest iterable is exhausted.
notes:
- This is mostly a passhtrough to Python's C(itertools.zip_longest) function
options:
_input:
description: Original list.
type: list
elements: any
required: yes
_additional_lists:

type: list

fillvalue:
description: Filler value to add to output when one of the lists does not contain enough elements to match the others.

EXAMPLES: |
# X_fill => [[1, "a", 21], [2, "b", 22], [3, "c", 23], ["X", "d", "X"], ["X", "e", "X"], ["X", "f", "X"]]
X_fill: "{{ [1,2,3] | zip_longest(['a','b','c','d','e','f'], [21, 22, 23], fillvalue='X') }}"

_value:
description: List of lists made of elements matching the positions of the input lists.
