Trouble with Hitpoints

is there anything i'm missing? also, can the player move diagonally in this scenario?
# 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
    for x in player:
        if x == -1:
            hp -= 5
            x = 0
        if x == 10:
            hp -= 5
            x = 9
    for y in player:
        if y == -1:
            hp -= 5
            y = 0
        if y == 10:
            hp -= 5
            y = 9
    return x, y, hp

I'm assuming the player can't move diagonally according to the examples.

But what you should be doing is checking the current position of the player, and the resulting position by applying the move in the specified direction. Now if that move turns out to be a valid move, you just return the new position and the same hitpoints. If not, you should keep the current player position and deduct the according number of hitpoints which your function returns. Checking if a move is valid would be if you apply the move, would the ending position be in the defined grid? I don't know the size of the defined grid, probably it was defined in the videos/challenges leading to this one.

Note that the input to the function is one of the three examples at a time (not all of them together), so there's no point in looping through the values of player, you already got the single values in variables x, y and hp respectively. And you should make sure your function would return the output as in the examples for the respective inputs, but still, one input and one output at a time.
