ansible -m ping all

Why am I getting the same warnings and Errors when I tried running my Playbook? (starfish.yml)

So, that means: My Playbook is Right? But something important is Not. What is that?  
Please Help…Thank You.

With Hope,  
Prabhakaran

The following are the Warnings and Errors:  
/usr/lib/python2.7/site-packages/ansible/parsing/vault/\__init_.py:44: CyptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in a future release.
