I have some machines with different properties and different installed versions of Python. Now I want to write a task that returns all available Python versions on every machine (some have 2.7.x, some 3.8.x and others are in between).
Depending on that I want to register the highest version for later tasks.
I tried to filter the output of ansible_facts.packages but I fail at using filters in YAML.
- name: Gather the package facts
ansible.builtin.package_facts:
manager: auto
strategy: all
- name: Check whether a package called python is installed
ansible.builtin.debug:
msg: "{{ ansible_facts.packages['python*'] }} versions of foobar are installed!"
I need it to return the machine and every Python version on that specific machine.

if all keys are selected which begins with python. One may also have a look into the output of
- debug:
msg: "{{ ansible_facts.packages.keys() }}"
The issue with the initial question was ansible_facts.packages['python*'], as globbing in the variable name and the dict will not work. One need to select the dict keys differently and as shown above.
