In Exercises 79 and 80, use the file USPres.txt discussed in Example 10

Example 10 True or False

The following program illustrates the truth values of objects.

## Illustrate Boolean values. if 7: print("A nonzero number is true.") else: print("The number zero is false.") if []: print("A nonempty list is true.") else: print("An empty list is false.") if ["spam"]: print("A nonempty list is true.") else: print("The empty list is false.")

83. Supreme CourtThe following list contains the members of the U.S. Supreme Court at the beginning of 2015. Each name is followed by a letter giving the political party (Republican or Democratic) of the president who appointed them.

justices = ["Scalia R", "Kennedy R", "Thomas R", "Ginsburg D", "Breyer D", "Roberts R", "Alito R", "Sotomayor D", "Kagan D"]

Write a program that creates two lists (one of Democratic appointees and one of Republican appointees) and uses the lists to produce the output shown in Fig. 3. 78.

Democratic appointees: Ginsburg, Breyer, Sotomayor, Kagan Republican appointees: Scalia, Kennedy, Thomas, Roberts, Alito
