A loop with subelements
<https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_loops.html#with-subelements>
should give you the control you need to template out what you need based on
the number of files in the data structure:
- name: test jinja rendering
> hosts: localhost
> gather_facts: no
>
> vars:
> users:
> - username: user1
> action: GET
> files:
> - file1
> - username: user2
> action: GET
> files:
> - file1
> - file2
>
> tasks:
> - name: debug the data structure
> ansible.builtin.debug:
> msg:
> - Item 0 is '{{ item.0 }}'
> - Item 1 is '{{ item.1 }}'
> loop: '{{ users | subelements("files") }}'
>
Sample debug output:
TASK [debug the data structure]
************************************************

['file1']}, 'file1']) => {

['file1']}'",
"Item 1 is 'file1'"
]
}
