movement.py? Not sure where to go from here?

This seems to return the correct values for player (x,y,hp) but I'm obviously missing something as it is not passing. Cheers

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
    a, b = direction
    if x + a > 0 and x + a < 10 and y + b > 0 and y + b < 10:
        x += a
        y += b
    else:
        hp -= 5

    return x, y, hp

Your test seems to be overly restrictive.

The challenge says to "Consider the grid to be 0-9 in both directions.", but you're only allowing movement within the range of 1-9. You're not allowing movement onto the 0 row or column, as in the first example.
