Create jinja template from dictionary in ansible

Question

how can I access stdout and item values in a dictionary?

My inventory file:

all:
  hosts:
    server1:
      dict:
        custom_mountpoints:
          - /srv/sftp
          - /opt
    server2:
       dict:
        custom_mountpoints:
          - /srv/sftp
          - /opt

My ansible task:

- name: Genarate OIDs for custom inventroy variables
  become: yes
  shell: 'snmptranslate -On NET-SNMP-EXTEND-MIB::nsExtendOutput1Line.\"{{ item[1] }}-{{ item[0] }}\"'
  loop: "{{ dict.custom_mountpoints | product(snmp_mountpoints_extends) | list }}"

  register: custom_mountpoints_output
  when:
    - dict is defined

- name: print output from custom_mountpoints_output
  debug: msg={{ custom_mountpoints_output }}

Output from custom_mountpoints_output variable:

ok: [server01] =>
 msg:
   changed: true
   msg: All items completed
   results:
   - ansible_loop_var: item
     changed: true
     cmd: snmptranslate -On NET-SNMP-EXTEND-MIB::nsExtendOutput1Line.\"folder-size-/srv/sftp\"
     delta: '0:00:00.015394'
     end: '2022-04-28 11:40:29.130234'
     failed: false
     invocation:
       module_args:
         _raw_params: snmptranslate -On NET-SNMP-EXTEND-MIB::nsExtendOutput1Line.\"folder-size-/srv/sftp\"
         _uses_shell: true
         argv: null
         chdir: null
         creates: null
         executable: null
         removes: null
         stdin: null
         stdin_add_newline: true
         strip_empty_ends: true
         warn: false
     item:
     - /srv/sftp
     - folder-size
     rc: 0
     start: '2022-04-28 11:40:29.114840'
     stderr: ''
     stderr_lines: []
     stdout: .1.3.6.1.4.1.8072.1.3.2.3.1.1.21.102.111.108.100.101.114.45.115.105.122.101.45.47.115.114.118.47.115.102.116.112
     stdout_lines:
     - .1.3.6.1.4.1.8072.1.3.2.3.1.1.21.102.111.108.100.101.114.45.115.105.122.101.45.47.115.114.118.47.115.102.116.112

etc. for each snmp_mountpoints_extends

then I try to access only stdout value:

- name: print output from custom_mountpoints_output
  debug:
    msg: "{{ item.stdout }}"
  loop: "{{ custom_mountpoints_output.results }}"
  register: output

become the following output:

ok: [server1] => (item={'cmd': 'snmptranslate -On NET-SNMP-EXTEND-MIB::nsExtendOutput1Line.\\"folder-size-/srv/sftp\\"', 'stdout': '.1.3.6.1.4.1.8072.1

etc.

But i would like to create a jinja template that write for me the following output in the file:

Hostname from a inventory file
 /srv/sftp\
 folder-size
 extend: value of stdout (.1.3.6.1.4.1.8072.1.3.2.3.1.1.21.102.111.108.100.101.114.45.115.105.122.101.45.47.115.114.118.47.115.102.116.112)

I try with following code:

{% for i in groups['all'] %}
Servername:  {{ hostvars[i].inventory_hostname }}
 {% for dict_item in output %}
   {% for item in dict_item.values() %}
 {{ item.value.msg }}
   {% endfor %}
 {% endfor %}
 {% for item in output.values() %}
 Extend: {{ output[item].stdout }}
 {% endfor %}
{% endfor %}

But it didn't work. Any idea how can i implement this with ansible and jinja?
