Hit Points Challenge: help with coordinating the coordinates and direction

I was hoping to get some critique on my attempt attached to this post: I think I have the main components necessary, but I am not sure what is out of order, or nested improperly.

movement.py
# EXAMPLES:
# move((1, 1, 10), (-1, 0)) => (0, 1, 10)
# move((0, 1, 10), (-1, 0)) => (0, 1, 5)
# move((0, 9, 5), (0, 1)) => (0, 9, 0)

def move(player, direction):
    x, y, hp = player

    if direction == "LEFT":
        x -= 1
    if direction == "RIGHT":
        x += 1
    if direction == "UP":
        y -= 1
    if direction == "DOWN":
        y += 1

def get_moves(player):
    moves = ["LEFT", "RIGHT", "UP", "DOWN"]
    if x == 0:
        moves.remove("LEFT")
    if x == 9:
        moves.remove("RIGHT")
    if y == 0:
        moves.remove("UP")
    if y == 9:
        moves.remove("DOWN")
    return moves

    if direction not in moves:
        hp -= 5

    return x, y, hp

The instructions tell you that the function will take a "three-part tuple player and a direction tuple that's two parts". Also, if you look at the comments in the boilerplate code, you'll see examples of how the function will be called.

It looks like your function is expecting "direction" to be a string with a descriptive word instead of the tuple containing the offset values. You'll need a significantly different approach to handle the arguments that will be provided.
