def display_list(listname):
    for element in listname:
        items = element.split(',')
        print(f"{items[0]:20} {items[1]:2} {items[2]:5}")

def main():
    mycities = ['Cape Girardeau,MO,63780','Columbia,MO,65201',
                'Kansas City,MO,64108','Rolla,MO,65402',
                'Springfield,MO,65897','St Joseph,MO,64504',
                'St Louis,MO,63111', 'Ames,IA,50010', 'Enid,OK,73773',
                'West Palm Beach,FL,33412',
                'International Falls,MN,56649',
                'Frostbite Falls,MN,56650'
                ]
    display_list(mycities)
