I wanted to know how to edit this code to make it loop back to the beginning. Its just a number comparison.

num1 = 0
num2 = 0

print "Hello, im a number comparison program "

num1 = input("Enter a number ")
num2 = input("Enter another number ")

if (num1 > num2):
    print "Your first number is greater"

if (num2 > num1):
    print "Your second number is greater"

if (num1 == num2):
    print "Your numbers are equal"

here is how i want to finish it in pseudo-code:

 "Enter another? (Yes or No) > "

if yes loop to beginning
if no print "Goodbye :)"

any help?

Yea i figured it out.

num1 = 0
num2 = 0
menuOption = ""

print "Hello, I'm a number comparison program "
while (menuOption != "n"):
     num1 = input("Enter a number> ")
     num2 = input("Enter another number> ")

     if (num1 > num2):
          print "Your first number is greater"

     if (num2 > num1):
          print "Your second number is greater"

     if (num1 == num2):
          print "Your numbers are equal"

menuOption = raw_input("Enter another number? (y/n)> ")

menuOption = raw_input("Enter another number? (y/n)> ")

is never executed and thus, menuOption cannot be set to "n" by the user.

it prompts me if i want to enter another number....so it seems to work. Basically while menuOption is not equal to "n" it'll loop.

This is why python is fun (using whitespace as syntax)

num1 = 0
num2 = 0
menuOption = ""

print "Hello, I'm a number comparison program "
while (menuOption != "n"):
     num1 = input("Enter a number> ")
     num2 = input("Enter another number> ")

     if (num1 > num2):
          print "Your first number is greater"

     if (num2 > num1):
          print "Your second number is greater"

     if (num1 == num2):
          print "Your numbers are equal"

     menuOption = raw_input("Enter another number? (y/n)> ")

It needs to be in the while loop. Maybe it is in your editor but it failed to copy/paste correctly.

while(1):
    #your code
    prompt for answer if done:
        break
exit(0)

remember to add error checking for the answer

sorry for the double post but this is that roman numeral converter i made today too.

list = ['I','II','III','IV','V','VI','VII','VIII','IX','X']
number = 0
menuOption = "" 

print "Hello, Im a roman numeral conversion program"

while (menuOption != "n"):
    number = input("Enter a number to be converted> ")
    if (number < 1):
        print "ERROR - Can't convert numbers less than or equal to zero"
    if (number > 10):
        print "ERROR - Can't convert numbers over 10"
    if (number <= 10 and number >= 1):
        print list[number - 1]

    menuOption = raw_input("Run again y/n > ")
if (menuOption == "n"):
    print "Goodbye :)"

#set vaules
list = ['I','II','III','IV','V','VI','VII','VIII','IX','X']
number = 0

#init
print "Hello, Im a roman numeral conversion program"

while (1):
    number = input("Enter a number to be converted> ")
    if (number < 1):
        print "ERROR - Can't convert numbers less than or equal to zero"
    if (number > 10):
        print "ERROR - Can't convert numbers over 10"
    if (number <= 10 and number >= 1):
        print list[number - 1]

    menuOption = raw_input("Run again y/n > ")
    if (menuOption == "n"):
    print "Goodbye :)"
    break
#end

also I would suggest 4 spaces in replacement of tabs when you're working with python.

forgot to declare menuOption :P

ok so its just good habbit to insert 'break' at the end of a loop

Actually it would be a bad habit to use a break like that. Use of break is generally discouraged. Essentially, a break is very similar to the infamous 'goto' and should be avoided unless necessary.

in this case you'd be right, but if theres a complicated check required a function+break would be better

code should be easy to read, remember that and you'll do fine
