Parse an AWS ARN (Amazon Resource Name) into it's constituent elements
def parse_arn(arn):
elements = arn.split(':')
result = {'arn': elements[0],
'partition': elements[1],
'service': elements[2],
'region': elements[3],
'account': elements[4]
if len(elements) == 7:
result['resourcetype'], result['resource'] = elements[5:]
elif '/' not in elements[5]:
result['resource'] = elements[5]
result['resourcetype'] = None
result['resourcetype'], result['resource'] = elements[5].split('/')
return result

This will parse at least rds auto snapshots' arns. they have ":" in the resource

I've created a similar library package for Go called awsarn, hope you don't mind too much if I leave a breadcrumb trail here :)
