for this part in the dungeon game im getting an error to do with the input function?

monster, door, player = get_locations()
while True: valid_moves = get_moves(player) clear_screen() print("Welcome to the dungeon!") print("You're currently in room {}".format(player)) #fill with player position print("You can move {}".format(", ".join(valid_moves))) #fill with avalible moves print("Enter QUIT to quit")

move = input("> ")
move = move.upper()

if move == "QUIT":
    break
if move in valid_moves:
    player = move_player(player, move)
else:
    print("\n ** Walls are hard! Dont run into them! **\n")
    continue

Heres what in prints out:

Welcome to the dungeon! You're currently in room (3, 3) You can move LEFT, RIGHT, UP, DOWN Enter QUIT to quit

QUIT Traceback (most recent call last): File "Untitled.py", line 60, in <module> move = input("> ") File "<string>", line 1, in <module> NameError: name 'QUIT' is not defined
