ansible.builtin.unique filter – set of unique items of a list
Note
This filter plugin is part of ansible-core and included in all Ansible
installations. In most cases, you can use the short

unique 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 filter plugin name.
