As far as i can tell this code is working, what is wrong with it

I know i'm not checking if the direction tuple is only moves in one direction and at a magnitude of 1 but the error i receive is that the player isn't taking damage. However, running it on my own IDE shows that is does work.

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
    dx, dy = direction
    nx = x + dx
    ny = y + dy
    if nx == -1 or nx == 10 or ny == -1 or nx == 10:
        nx = x
        ny = y
        hp -= 5

    return nx, ny, hp

There is one small error in your code:

if nx == -1 or nx == 10 or ny == -1 or nx == 10:
                                        ^

should be:

if nx == -1 or nx == 10 or ny == -1 or ny == 10:
                                        ^
