Question

Code:

def Division():

    print "************************\n""********DIVISION********\n""************************"
    counter = 0
    import random
    x = random.randint(1,10)
    y = random.randint(1,10)
    answer = x/y
    print "What will be the result of " + str(x) + '/' + str(y) + " ?"
    print "\n"
    userAnswer = input ("Enter result: ")
    if userAnswer == answer:
        print ("Well done!")
        print "\n"
        userInput = raw_input ("Do you want to continue? \n Enter 'y' for yes or 'n' for no.")
        if userInput == "y":
            print "\n"
            Division()
        else:
            print "\n"
            Menu()
    else:
        while userAnswer != answer:
            counter += 1
            print "Try again"
            userAnswer = input ("Enter result: ")
            if counter == 3: break
        userInput = raw_input ("Do you want to continue? \n Enter 'y' for yes or 'n' for no.")
        if userInput == "y":
            print "\n"
            Division()
        else:
            print "\n"
            Menu()

In this case I want x value to be always bigger than y value. How to do I do it?
Code for subtraction is similar and the question remains the same, target is to avoid
negative result.

Answer 1

You can check if x < y and swap them e.g.

if x < y:
    x, y = y, x

Note in python you can swap two variables without need of a temporary variable.

You can even take further shortcut by using bultin min and max and do it in a single line e.g.

x, y = max(x,y), min(x,y)
