ansible.builtin.together – merges lists into synchronized list


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