Hello Venkat,

Yes of course, I suggest you take a look here:  
[https://docs.ansible.com/ansible/latest/user\_guide/playbooks\_conditionals.html](https://docs.ansible.com/ansible/latest/user_guide/playbooks_conditionals.html)

However, this list is not the proper place for such questions.  
I strongly recommend that you send such questions to the "ansible-project" mailing list.
