I am getting a syntax error for correct code?

I am currently doing 1.8 ‘Your own While/Else loop’ and when I run the code I get this error:

Traceback (most recent call last):
  File "runner.py", line 96, in compilecode
  File "python", line 8
    if guess==random_number:
                           ^
SyntaxError: invalid syntax

The code is:

from random import randrange
random_number = randrange(1, 10)
count = 0
while count < 3:
    guess=int(raw_input('Enter a guess:')
    if guess==random_number:
        print "you win!"
        break
    count+=1
else:
    print'you lose.'

I really have no idea what’s wrong with this code, can someone please help explain?
