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
plugin name
symmetric_difference
even without specifying the collections:

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.
