ansible.builtin.together – merges lists into synchronized list


This module is part of ansible-core and included in all Ansible installations. In most cases, you can use the short module name together even without specifying the collections: keyword. However, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

New in version 1.3: of ansible.builtin


  • Creates a list with the iterated elements of the supplied lists

  • To clarify with an example, [ ‘a’, ‘b’ ] and [ 1, 2 ] turn into [ (‘a’,1), (‘b’, 2) ]

  • This is basically the same as the ‘zip_longest’ filter and Python function

  • Any ‘unbalanced’ elements will be substituted with ‘None’
