[ansible]apt update && apt install tree

This can be applied to install package from apt repo.
I have three ubuntu servers under the group linux.

YAML file

---
- hosts: linux
  become: true
  become_user: root
  tasks:
   - name: apt update && apt install tree -y
     apt:
       update_cache: yes
       name: tree
       state: present
...

Execution

Result
The ansible python script is sent from the control node to the ubuntu servers, this is the default behaviour, unless the connection is like network_cli then the control node executes ssh to the network device which does not have python to execute the playbook.
