Finally, a database instance can be deleted by invoking the delete_db_instance() function call by passing the database instance identifier to it. 

The following code demonstrates how to delete a database instance:

#!/usr/bin/env python

import boto3

rds = boto3.client('rds')

try:
    response = rds.delete_db_instance(
        DBInstanceIdentifier="packtpub",
        SkipFinalSnapshot=True)
    print response
except Exception as error:
    print error

This concludes the basic operations on the Amazon RDS instance using application programming.
