aws_regions = [ ('us-east-1', 'use1', 'N. Virginia' ), ('us-east-2', 'use2', 'Ohio' ), ('us-west-1', 'usw1', 'N. California' ), ('us-west-2', 'usw2', 'Oregon' ), ('ca-central-1', 'cac1', 'Central' ), ('eu-west-1', 'euw1', 'Ireland' ), ('eu-west-2', 'euw2', 'London' ), ('eu-central-1', 'euc1', 'Frankfurt' ), ('ap-southeast-1', 'ase1', 'Singapore' ), ('ap-northeast-1', 'ane1', 'Tokyo' ), ('ap-northeast-2', 'ane2', 'Seoul' ), ('ap-southeast-2', 'ase2', 'Sydney' ), ('ap-south-1', 'aps1', 'Mumbai' ), ('sa-east-1', 'sae1', 'Sao Paulo' ), ] aws_regions_dict = {} for r in aws_regions: aws_regions_dict[r[0]] = r aws_regions_dict[r[1]] = rthis dictionary will have keys from both long names in the first column and short names in the second column. this is what i don't how to do in comprehsions.
