Ansible Python API - send file as parameter

[Balaji]

Hello All,

Can anyone please help to create an equivalent of a command 

ansible-playbook -i environments playbooks/site.yml -u user_name  -e "@build.json"

I am very curious to know how to write this  " -e "@build.json" " in python.

Background - I am trying to run above command from a python script.

Thanks,

Balaji Chavdi
