Looping through Ansible Register output and printing the result as list - ansible

Question

This is the sample task which give me the output which contains a list of self IPs. I want to capture this in Result and just print only the name of self IP.
I was able to print if I give a list index, but I can't loop through it to capture it as a separate list to use it in a different task.
- name: Port Lock Down - Allow Default
bigip_device_info:
gather_subset:
- self-ips
provider: "{{provider}}"
register: Result
- name : Display the selfips
debug:
var: Result

}
Can someone help me to use the for loop to get all the self IPs names as list instead of one single output?

You actually do not need a loop to achieve this, you can use the map filter of Jinja instead:
Result.self_ips | map(attribute='name')
Given the task:
- debug:
var: Result.self_ips | map(attribute='name')
vars:
Result:
self_ips:
- address: 3.3.3.3
allow_access_list:
- 'tcp:8080'
- 'udp:53'
- 'gre:0'
- default
floating: 'no'
full_path: /Common/test-self-ip-1
name: test-self-ip-1
- address: 4.4.4.4
allow_access_list: all
floating: 'no'
full_path: /Common/test-self-ip-2
name: test-self-ip-2
This yields the result:
Result.self_ips | map(attribute='name'):
- test-self-ip-1
- test-self-ip-2
