The following is my script:

import boto3
import json

BUCKET_NAME ='patricksbucket'

    s3 = boto3.client('s3')

    return s3_client().create_bucket(
        Bucket=bucket_name,
        CreateBucketConfiguration={
            'LocationConstraint': 'us-east-2'
            }
        )

        ]
    }
    policy_string = json.dumps(bucket_policy)

    return s3_client().put_bucket_policy(

    )
