[Python] Preoblikovanje programa

Rabim nekaj pomoči.Pred parimi dnevi sem se začel učiti Python in do sedaj je šlo vse OK.Danes in včeraj pa sem razmišljal kako bi preoblikoval naslednji program:

## 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 question 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 let's run the questions
run_test(get_questions())

In sicer:
a) imeti bi moral meni
b) v meniju bi morale biti opcije (poganjanja testa,izpisa vprašanj in odgovorov,dodajanja vprašanj in odgovorov,brisanje vprašanj in odgovorov in možnost izhoda)

S tem se j*** že vsaj 4 ure pa mi ni jasno kako bi to naredil,da bi delovalo.
