Use Ansible2.6 Python Api to perform playbook tasks

the following is the ansible api section:

    """A sample callback plugin used for performing an action as results come in

    If you want to collect all results into a single object for processing at
    the end of the execution, look into utilizing the ``json`` callback plugin

-sharp initialize needed objects

-sharp Instantiate our ResultCallback for handling results as they come in. Ansible expects this to be one of its main display outlets
results_callback = ResultCallback()

-sharp create inventory, use path to host config file as source or hosts in a comma separated string
inventory = InventoryManager(loader=loader, sources="localhost,")

-sharp variable manager takes care of merging all the different sources to give you a unifed view of variables available in each context

print(result)
 

the following is the playbook content:

- hosts: localhost
  remote_user: x.g
  become: yes
  become_method: sudo

  tasks:

        version: master
        key_file: /Users/gaox/.ssh/id_rsa

execution result:
