Ansible export to csv

Question

I want to get a csv with a list of new updates in this form:

testvm-001.localdomain,ImageMagick-6.9.11.27-4.el7

testvm-001.localdomain,ImageMagick-libs-6.9.11.27-4.el7

I have a code that will display a list of updates, but I don’t know how to save it in csv in the right form.

- hosts: test
  vars:
    my_packages: "{{ dict(packages.results|groupby('name')) }}"
  tasks:
    - name: Count new update
      shell: hostname
      register: hostname
    - dnf:
        list: updates
      register: packages
    - debug:
        msg: |
          {% for name,versions in my_packages.items() %}
          {% set max_ver=versions|map(attribute='version')|max %}
          {% set p=versions|selectattr('version', '==', max_ver) %}
          {{ hostname.stdout }},{{ name }}-{{ p.0.version }}-{{ p.0.release }}
          {% endfor %}
