Prior to writing your program, use PowerPoint to draw a UML diagram of the class.   An address has a house number, a street, an optional apartment number, a city, a state and a postal code. Define the constructor such that an object can be created in one of two ways: with our without an apartment number. Supply a print method that prints the address with the street on one line and the city, state and postal code on the next line. Supply a method def comesBefore(self, other) that tests whether this address comes before other when compared by postal code. This method should return a boolean value.
