using python 3:

def circleInfo(r): """ Return (circumference, area) of a circle of radius r """ c = 2 * 3.14159 * r a = 3.14159 * r * r return (c, a)

(circum, area) = circleInfo(10) print('area =', area) print('circumference =', circum)

t = circleInfo(10) print(t)

on next line after print(t) use the index operator (two times) to print the two elements of the tuple.

2.

actress = ( ("Julia", "Roberts"), (8, "October", 1967), [ ("Duplicity", 2009), ("Notting Hill", 1999), ("Pretty Woman", 1990), ("Erin Brockovich", 2000), ("Eat Pray Love", 2010), ("Mona Lisa Smile", 2003) ], ("Atlanta", "Georgia") )

print(type(actress[1])) print(actress[1]) for movies in actress:==line 12 print(actress[2:])

On new line (the body of the loop), display only the title of the movie. Run.

On line 12, append the movie (Oceans Twelve, 2004) to the list. Run and notice that, even though the tuple is immutable, we can change its list which is mutable.
