[Tutor] Lists within lists return

[Eve Kotyk]

I'm working through the Josh Cogliati tutorial on the Python site.  In
the secton on lists, example 8.3, test.py is given along with a sample
output.  I've typed up the program using Idle but I do not get the
expected output.  In fact I get no output at all and I don't get any
error messages.  Below see the example code as cut and pasted from my
file.  I would appreciate any help you might be able to give me.

##This program is called test.py
# This program runs a test of knowledge

true = 1
false = 0

#First get the test questions
#Later this will be modified to use file io.
def get_questions():
    #notice how the data is stored as a list of lists 
    return [["What color is the daytime sky on a clear day? ","blue"],\
    	["What is the answer to life, the universe and everything? ",
"42"]\
    	["What is a three letter word for mouse trap? ","cat"]]
    
    	
#This will test a single question
#it takes a single questin in
#it returns true if the user typed the correct answer, otherwise false
def check_question(question_and_answer):
    #extract the question and the answer from the list
    question = question_and_answer[0]
    answer = question_and_answer[1]
    #give the question to the user
    given_answer = raw_input(question)
    #compare the user's answer to the testers answer
    if answer == given_answer:
        print "Correct"
        return true
    else:
        print "Incorrect, correct was: ", answer
        return false
    
    #This will run through all the questions
    def run_test(questions):
        if len(questions) == 0:
            print "No questions were given."
            #the return exits the function
            return
        index = 0
        right = 0
        while index < len(questions):
            #Check the question
            if check_question(questions[index]):
                right = right + 1
                #go to the next question
                index = index + 1
        #notice the order of the computation, first multiply, then
divide
        print "you got ",right*100/len(questions), "% right out of",\ 		
len(questions)
    #now lets run the questions
    run_test(get_questions())
