Hi,

I am a newbie to the Ansible Python API thing and i am trying out to run the code given in the Ansible Python API documentation (Link: [http://docs.ansible.com/ansible/developing\_api.html](http://docs.ansible.com/ansible/developing_api.html) Python API 2.0)

I get the following error:

Can you please let me know how to proceed with this?
