Here you guess once.

If you guessed correctly, the game ends.

You ask the user to try again, but you pay no attention to their reply. 
You just completely ignore their guesses, apart from the very first one.

Also, and by the way, although Python does have a "while...else" 
construct, it's a bit misleading and I don't think it is useful in this 
case.

Experiment with something like this instead:


rand_value = random.randint(1,10)
guess = 0  # Guaranteed not to match.
while guess != rand_value:
    guess = input("Guess a number between one and ten: ")

print("Congratulations!")



Notice that each time through the loop, I set guess to a new value?
