Trying To Loop Just Some Parts Of A Math Quiz Program

I'm trying to figure out the best way to loop this simple math quiz program (best here meaning the neatest and simplest method). I get two random numbers and their sum, prompt the

Solution 1:

You're missing two things here. First, you need some sort of loop construct, such as:

while <condition>:

Or:

for <var> in <list>:

And you need some way to "short-circuit" the loop so that you can start again at the top if your user types in a non-numeric value. For that you want to read up on the continue statement. Putting this all together, you might get something like this:

While True:
    add1 = random.randint(1, 10)
    add2 = random.randint(1, 10)
    answer = str(add1 + add2)


    question = "What is %d + %d?" % (add1, add2)
    print question
    print answer

    userIn = raw_input("> ")

    if userIn.isdigit() == False:
        print"Type a number!"# Start again at the top of the loop.continueelif userIn == answer:
        print"AWESOME"else:
        print"Sorry, that's incorrect!"print"Play again? y/n"
    again = raw_input("> ")

    if again != "y":
        break

Note that this is an infinite loop (while True), that only exits when it hits the break statement.

In closing, I highly recommend Learn Python the Hard Way as a good introduction to programming in Python.

Solution 2:

There are two basic kinds of loops in Python: for loops and while loops. You would use a for loop to loop over a list or other sequence, or to do something a specific number of times; you would use a while when you don't know how many times you need to do something. Which of these seems better suited to your problem?
