Why even initialize it?  You never modify it, and it's only used inside
the while: loop.

[ snippage ]

Not much chance of this happening. Only in Perl is "6" == 6.  <wink>

How bout this:

def print_options():
    print """Options:
    1   Print Options
    2   Add numbers
    3   Subtract numbers
    4   Multiply number
    5   Divide number
    6   Exit
    """         # easier to read, and prints prettier, too! <wink>

print_options()

while 1:                    # this is what happens anyway
    choice = raw_input("What would thou like to do? ")
    if choice == "6":       # get it out of the way
        break               # sometimes sys.exit() ~ GOTO
    elif choice == "1":
        print_options()
    elif choice == "2":
        add = input("What number would you like to add? ")
        add2 = input("What other number do you want to add? ")
        print "The awnser is", add + add2
    elif choice == "3":
        sub = input("What number do you want to subtract? ")
        sub2 = input("What 2nd number do you want to subtract? ")
        print "Your awnser is,", sub + sub2
    elif choice == "4":
        mul = input("What number do you want to multiply? ")
        mul2 = input("What 2nd number do you want to multiply? ")
        print "Your multiplicated number is", mul * mul2
    elif choice == "5":
        div = input("What is your dividend? ")
        div2 = input("What is your numerator? ")
        print "Your awnser is", div/div2

print "thanks for using my program"
