Create a dictionary that maps countries to their capitals. You may start with an empty dictionary. Ask the user to input the name of the country and its capital and add them to the dictionary.

E.g., capitals = { ' Argentina':'Buenos Aires', 'France':'Paris', 'US': ' Washington D.C.'}

Once the dictionary is created, print the capitals in alphabetical order.
