ansible.builtin.indexed_items – rewrites lists to return ‘indexed items’

Note

This lookup plugin is part of ansible-core and included in all Ansible installations. In most cases, you can use the short plugin name indexed_items 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
