If-else if statement not working properly

Question

I am trying to make a multiplication game for my sister, but my code doesn't go through if-else statements properly. I have no idea why this is so. Can someone tell what I am doing wrong?

from random import randint

print "Welcome to Multiplication Practice."
print "\n-------"

correct = 0

wrong = 0

while wrong<3:

    a = randint(1,9)
    b = randint(1,9)
    print "What is %s x %s?" %(a,b)
    c = a * b
    action = raw_input("> ")
    if action == c:
        print "correct!"
        correct +=1

    elif  action != c:
        print "Wrong!"
        wrong +=1

    else:
        print "Invalid answer."

print correct 

print wrong

Answer 1

raw_input returns a string. This will never compare equal to a number. You need to convert the entered string to a number:

action = int(raw_input("> "))

Answer 2

raw_input始终返回一个字符串，您需要将其转换为要与之比较的类型，在这种情况下，它是int(raw_input("> "))
