I have a playbook that looks like the following. It is supposed to install python onto the remote machine so that it can start using modules, hence why I have it using raw since it is the only thing that will run without a python interpreter.
---
- name: Checking Ansible Python Dependency
hosts: Debian_Buster
gather_facts: False
tasks:
- name: install python 2
become: yes
raw: test -e /usr/bin/python || (apt -y update && apt install -y python-minimal)
This playbook task works as expected, but always returned "changed", even when nothing was installed.
Is there a way i can make this playbook return "ok" when test -e /usr/bin/python returns 0, and then return 'changed' when test -e /usr/bin/python returns 1?
Note: I can not use any other module other than raw because the python dependency is not available.

The basic solution to this kind of problem makes use of the register keyword to save the result of the task, and then inspect the result in a changed_when expression.
In your case, we cannot use the return code alone to decide this, but we could just inspect the standard output, which, correct me if I am wrong, should only be empty if the test command succeeded.
Example:
- name: install python 2
become: yes
raw: test -e /usr/bin/python || (apt -y update && apt install -y python-minimal)
register: command_result
changed_when: command_result.stdout | length > 0

Exactly what i needed. I found the changed_when option and got it to work, but my play was much longer than yours. Thank you for showing me best practice :)
