title = "Guess my number game:"
print title.title()
raw_input("Press any key to continue..")

import random

tries = 0
number = random.randrange(99) + 1
guess = int(raw_input("Guess my number! Secret - It is between 1 and 100 :")

while (guess != number):
if (guess > number):
    number = int(raw_input("Sorry, my number is lower than that! \n Try again:")
   tries += 1
else if (guess < number):
    number = int(raw_input("Sorry, my number is higher than that! \n Try again:")
    tries += 1
print "Congratulations, you guessed my number! \n And it only took you" tries "tries!"

raw_input("\n\n Press any key to exit..")

## what is wrong with this script? I'm just trying to understand while loops and ## this is not a real project :P
