Using Python

Create a dictionary named states that uses two-letter state abbreviations as keys.

Each value in the states dictionary should be a list holding both the state name and state capital city.

Add at least a dozen states to the dictionary,

Loop through the entire dictionary showing the state abbreviation, state name, and state capital

Then, create a quiz using another loop to ask for state capitals.

Provide feedback to the user after each quiz question.

CA state is California capital city is Sacramento
NY state is New York capital city is New York
...

Explanation / Answer

import hashmap

# create a mapping of state to abbreviation
states = hashmap.new()
hashmap.set(states, 'Oregon', 'OR')
hashmap.set(states, 'Florida', 'FL')
hashmap.set(states, 'California', 'CA')
hashmap.set(states, 'New York', 'NY')
hashmap.set(states, 'Michigan', 'MI')

# create a basic set of states and some cities in them
cities = hashmap.new()
hashmap.set(cities, 'CA', 'San Francisco')
hashmap.set(cities, 'MI', 'Detroit')
hashmap.set(cities, 'FL', 'Jacksonville')

# add some more cities
hashmap.set(cities, 'NY', 'New York')
hashmap.set(cities, 'OR', 'Portland')

# print out some cities
print '-' * 10
print "NY State has: %s" % hashmap.get(cities, 'NY')
print "OR State has: %s" % hashmap.get(cities, 'OR')

# print some states
print '-' * 10
print "Michigan's abbreviation is: %s" % hashmap.get(states, 'Michigan')
print "Florida's abbreviation is: %s" % hashmap.get(states, 'Florida')

# do it by using the state then cities dict
print '-' * 10
print "Michigan has: %s" % hashmap.get(cities, hashmap.get(states, 'Michigan'))
print "Florida has: %s" % hashmap.get(cities, hashmap.get(states, 'Florida'))

# print every state abbreviation
print '-' * 10
hashmap.list(states)

# print every city in state
print '-' * 10
hashmap.list(cities)

print '-' * 10
state = hashmap.get(states, 'Texas')

if not state:
print "Sorry, no Texas."

# default values using ||= with the nil result
# can you do this on one line?
city = hashmap.get(cities, 'TX', 'Does Not Exist')
print "The city for the state 'TX' is: %s" % city
