How to create a s3 bucket using Boto3?

I want to enable cloudtrail logs for my account and so need to create an s3 bucket.I wanted to automate this task using Boto3.Currently I am using the following script

sess = Session(aws_access_key_id=tmp_access_key,
                   aws_secret_access_key=tmp_secret_key, aws_session_token=security_token)  
s3_conn_boto3 = sess.client(service_name='s3', region_name=region)  

bucket = s3_conn_boto3.create_bucket(Bucket=access_log_bucket_name,
                                                     CreateBucketConfiguration={'LocationConstraint':'us-east-1'},
                                                     ACL='authenticated-read',..).

I am new to Boto3 so I don't have much knowledge regarding usage of other parameters like GrantWrite,GrantWriteACP etc..

Please help me provide some code snippet regarding create s3 bucket and enabled cloudtrail logs in it.

Thanks
