Title Body

In php, one can handle a list of state names and their abbreviations with an associative array like this: <?php $stateArray = array( "ALABAMA"=>"AL", "ALASKA"=>"AK", // etc... "WYOMING"=>"WY" ); foreach ($stateArray as $stateName => $stateAbbreviation){ print "The abbreviation for $stateName is $stateAbbreviation.\n\n"; } ?> Output (with key order preserved): The abbreviation for ALABAMA is AL. The abbreviation for ALASKA is AK. The abbreviation for WYOMING is WY. EDIT: Note that the order of array elements is preserved in the output of the php version. The Java implementation, using a HashMap, does not guarantee the order of elements. Nor does the dictionary in Python. How is this done in java and python? I only find approaches that supply the value, given the key, like python's: stateDict = { "ALASKA": "AK", "WYOMING": "WY", } for key in stateDict: value = stateDict[key] EDIT: based on the answers, this was my solution in python, # a list of two-tuples stateList = [ ('ALABAMA', 'AL'), ('ALASKA', 'AK'), ('WISCONSIN', 'WI'), ('WYOMING', 'WY'), ] for name, abbreviation in stateList: print name, abbreviation Output: ALABAMA AL ALASKA AK WISCONSIN WI WYOMING WY Which is exactly what was required.
