boto short to long region names for use with AWS pricing API

short2long_regions.py

# Get the long region names used by the AWS Pricing API
#
# There's currently no proper API to do this
#
# Example:
# print(SHORT_TO_LONG_REGIONS['us-west-2'])
# > US West (Oregon)

from pkg_resources import resource_filename

endpoints_file = resource_filename('botocore', 'data/endpoints.json')

with open(endpoints_file, 'r') as f:
    endpoints = json.load(f)

SHORT_TO_LONG_REGIONS = {k: v['description'] for k, v in next(iter(endpoints.get('partitions', [])), {}).get('regions', {}).items()}
SHORT_TO_LONG_REGIONS['eu-west-1'] = 'EU (Ireland)'
SHORT_TO_LONG_REGIONS['eu-central-1'] = 'EU (Frankfurt)'
SHORT_TO_LONG_REGIONS['eu-north-1'] = 'EU (Stockholm)'
SHORT_TO_LONG_REGIONS['eu-west-2'] = 'EU (London)'
SHORT_TO_LONG_REGIONS['eu-west-3'] = 'EU (Paris)'

Unfortunately this works for newer regions, but the older EU regions don't work. I've had to have overrides for these:

SHORT_TO_LONG_REGIONS['eu-west-1'] = 'EU (Ireland)'
SHORT_TO_LONG_REGIONS['eu-central-1'] = 'EU (Frankfurt)'
SHORT_TO_LONG_REGIONS['eu-north-1'] = 'EU (Stockholm)'
SHORT_TO_LONG_REGIONS['eu-west-2'] = 'EU (London)'
SHORT_TO_LONG_REGIONS['eu-west-3'] = 'EU (Paris)'

Issue was raised with AWS but no plans on fixing it either :/ See boto/botocore#2078

Thank you for the heads up! I updated the Gist with your workaround. The discussion in that botocore issue is just sad to read 🙁
