Ansible loop over list extracted from dict

I'm using Ansible 2.9 on RHEL 7.7, and I'm trying to loop over a list which is a value from a dict element. So far I have this var file and play:

ssh_keys:
  account: blah
  permissions: 600
  keys:
    - qa-publickeys['1']
    - qa-publickeys['2']
    - qa-publickeys['3']

the play:

- name: Traversing ssh keys 
  debug:
    msg: "Here's: {{ item }}"
  loop: "{{ ['keys'] | map('extract', ssh_keys) | list }}"

The problem is, msg is "msg": "Here's: [u\"qa-publickeys['1']\", u\"qa-publickeys['2']\", u\"qa-publickeys['3']\"]"

Why is it not giving me three outputs, with Here's: qa-publickeys['1'] as the first output, Here's: qa-publickeys['2'] as the second, and finally Here's: qa-publickeys['3'] ?

The list that I present to the loop in this play is not getting looped over, it's just iterating once in one chunk.

You seems to make is really complex for yourself for no apparent reason.
A dictionary in Ansible can be accessed via either the . dot notation or the [] square brackets notation.

Now because .keys() is indeed a built-in method of a dictionary in Python, you cannot use the first notation, but you can use the later one.

Given the playbook:

- hosts: all
  gather_facts: no

  tasks:
    - debug:
        msg: "Here's: {{ item }}"
      loop: "{{ ssh_keys['keys'] }}"
      vars:
        ssh_keys:
          account: blah
          permissions: 600
          keys:
            - qa-publickeys['1']
            - qa-publickeys['2']
            - qa-publickeys['3']

This yields the recap:

PLAY [all] *******************************************************************************************************

TASK [debug] *****************************************************************************************************
ok: [localhost] => (item=qa-publickeys['1']) => 
  msg: 'Here''s: qa-publickeys[''1'']'
ok: [localhost] => (item=qa-publickeys['2']) => 
  msg: 'Here''s: qa-publickeys[''2'']'
ok: [localhost] => (item=qa-publickeys['3']) => 
  msg: 'Here''s: qa-publickeys[''3'']'

PLAY RECAP *******************************************************************************************************
localhost                  : ok=1    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0
