Hi all 

I am python beginner I am trying the below code and getting incorrect syntax in python (3.3.2)

number = 23
running = True
while running:
guess = int(raw_input('Enter an integer : '))
if guess == number:
print ("Congratulations, you guessed it.")
running = False # this causes the while loop to stop
elif guess < number:
print ("No, it is a little higher than that.")
else:
print ("No, it is a little lower than that.")
else:
print ("The while loop is over.")
# Do anything else you want to do here
print ("Done")

Please help me with this 

Thank you in advance
