Thank Dick…Thank you for your kindness…  
Sorry if I confused. My intention is to run the playbook and get all the hostnames in a variable .

Like :  
var=hostvars[ansible\_hostname][‘ansible\_hostname’]

With the above command I can fetch the hostname but how to append all the hostnames in an array so that finally I can pass that array to python script.

Regards

I would write an Ansible module from the Python script and do the rest in Ansible. Anyways, check [https://docs.ansible.com/ansible/latest/reference\_appendices/special\_variables.html#magic-variables](https://docs.ansible.com/ansible/latest/reference_appendices/special_variables.html#magic-variables) for ansible\_play\_hosts and ansible\_play\_hosts\_all
