How to set a variable using dynamic inventory using Ansible

[Rahul Mehrotra]

I am looking for method to set a variable in ansible playbook using inventory information received from dynamic inventory. 

For example if we have a sample playbook like

    ---

    - hosts: localhost

      connection: local

      

      tasks:

       - set_fact: rds_hostname="{{ rds_mysql }}" #set rds endpoint from ec2.py

       

       - debug: var=rds_hostname 

      

I am able to get the endpoint when I run the plain ec2.py script as

> "rds_mysql":{

>> "rds_mysql.shdahfiahfa.us-easy-1.rds.amazon.com"

> }

However I wish to set rds_hostname as the endpoint recieved from dynamic_inventory. 

Can any one point out my mistake. Thank you

what is rds_mysql in this context? it is not clear that it is returned
as a hostvar/groupvar or something else
