Retrieving items from a dictionary

I am trying to look at our server mounts and only show those that have a specific mount available. The playbook is as follows:

Map the attribute

  dn: "{{ ansible_mounts|
          selectattr('device', 'contains', 'nas-server.example.com')|
          map(attribute='device') }}"

If you want to skip empty lists test the length

  - debug:
      var: dn
    when: dn|length > 0

Thank you Vladimir! I had already gotten the selectattr piece working but the length check was the missing piece. All good now.

Thanks,
Harry
