HP: hmm can't find a the problem. Function passes when I pass various values through it.

I passed this through my function and got the values I expected:

move((9, 5, 15), "RIGHT") (9, 5, 10) move((0, 8, 10), "LEFT") (0, 8, 5) move((1, 0, 10), "UP") (1, 0, 5) move((5, 9, 10), "DOWN") (5, 9, 5)

move((5, 8, 10), "DOWN") (5, 9, 10) move((1, 1, 10), "UP") (1, 0, 10) move((1, 8, 10), "LEFT") (0, 8, 10) move((8, 5, 15), "RIGHT")

thinking maybe I am using "direction" wrong, but now I'm thinking in a box I can't get out of.

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 x <= -1:
            hp = hp - 5
            x = 0
    if direction == "RIGHT":
        x += 1
        if x >= 10:
            hp = hp-5
            x = 9
    if direction == "UP":
        y -= 1
        if y <= -1:
            hp = hp - 5
            y = 0
    if direction == "DOWN":
        y += 1
        if y >= 10:
            hp = hp-5
            y = 9

    return x, y, hp

You seem to be expecting "direction" to be a string with an upper-case word.

But the instructions say the function should take "a direction tuple that's two parts, the x to move and the y (like (-1, 0) would move to the left but not up or down)."

So instead of :point_right: move((1, 1, 10), "LEFT")
you might get :point_right: move((1, 1, 10), (-1, 0))

Also see the examples provided in the comments.

haha i assumed that would be taken from another function that took the player's input.

fine I will check the comments later then...I don't like going straight to an answer.

I'm not sure what you mean by "straight to an answer". The "EXAMPLES" section in the comments (shown in the code above) only illustrate how the method might be called.
