CSCI 150 HW 3: function reading practice

You should complete the following exercises without using a computer, though you may consult your textbook. You should write your answers by hand and turn them in on paper.

1. Consider the functions defined below. What does main() print?

   def foo(a):
       b = 3*a + 2
       return b
   
   def bar(x,y):
       return foo(x) + foo(y)
   
   def main():
       print "The value is " + str(bar(2,3))

2. Consider the functions defined below. What is printed by main2()?

   def f1():
       print "mushroom"
   
   def f2():
       f1()
       print "badger"
       f1()
   
   def f3(n):
       f2()
       if n > 5:
           print "snake"
           f1()
       else:
           print "snaaaaake"
   
   def main2():
       f3(2)
       f3(6)
