Create New request using Python Script fails

Hi Team,
I wanted to create a new request ticket using python script, to automatically create tickets in daily basis.
I have gone through the below API reference page,

Can the someone try and share the sample python script to create a new request ticket.

script sample attached, i am getting the below error

Error: {"response_status":{"status_code":4000,"messages":[{"status_code":4001,"field":"input_data","type":"failed","message":"Value not provided"}],"status":"failed"}}
