I am trying to create basic survey program that asks questions and takes a numerical result from the answer and finds the average. i.e. A=10, B=5, C=0. I'm having two basic problems, the first and more important is adding the result to the list. The second is a formatting issue: I keep receiving an 'unexpected indent' or 'indent does match outer indentation layer' error on the append lines. I would appreciate any thoughts.
analyzing simple survey data for political affiliation
voter = list()
def question_1(x):
    if x == "A":   
        print 10
        voter.append(10)   
    elif x == "B":
        print 5
        voter.append(5)
    elif x == "C":
        print 0
        voter.append(0)
    else:
        print "Not a valid answer"
 
def question_2(y):  
    if y == "A":
        print 10
        voter.append(10)
    elif y == "B":
        print 5
        voter.append(5)
    elif y == "C":
        print 0
        voter.append(0)
    else:
        print "Not a valid answer"
def question_3(z):
    if z == "A":
        print 10
        voter.append(10)

        voter.append(5)
