ansible.builtin.symmetric_difference filter – different items from two lists
Note
This filter plugin is part of ansible-core and included in all Ansible
installations. In most cases, you can use the short

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.
