Yes. Or if you feel like ignoring the warnings^* about using variables
in copy's "content":
- name: Write to the file
ansible.builtin.copy:
content: |
{% for server in servers %}
{{ server }}
{% endfor %}
dest: "{{my_inv}}"
^* I do it quite often, looking for cases where the promised unexpected
surprises happen, but I haven't found them yet. It'll probably happen
some day when it least convenient. :)

I mean, what does the output of

ansible.builtin.debug:

look like? It presumably has a 'json' field? Which itself
contains a 'value'?
Without a reasonable approximation of your input, I can't
possibly suggest how to create expected output from it.

While collecting the inventory from a dynamic
source , I am able to filter the hostname and
print them as below as expected.
servera
serverb
serverc
serverd
when set to facts with set_fact also fine and
print in the order one below the other.
However when I try to write into a file with copy
module ,
- name: Write to the file
ansible.builtin.copy:
content: "{{ result['json']['value']
|map(attribute='hostname') }}"
dest: "{{my_inv}}"
the format collapses as below.
'servera', 'serverb', 'serverc', 'serverd'
How can I write the output in the list
format(line by line) as this file will be used
to read as an inventory for other tasks .
