short code to list AWS regions

[Skaperen]

this is some short code (148 bytes on a NL text system, 150 bytes on a CRLF system) to list the names of AWS regions. to use this you need:
* an AWS account (free for one year)
* set up your credentials for boto3 or botocore to use
* installed boto3 or botocore (in PyPI so pip can do it)

import botocore.session
print('\n'.join(r['RegionName']for r in botocore.session.get_session().create_client('ec2').describe_regions()['Regions']))

(if you already have boto3 then you already have botocore)
this is only tested on Ubuntu Linux but it should also work on other OSes.
