Python Python Collections (2016, retired 2019) Dungeon Game Hit points

mm, didn't get the right movement results. Hitting a wall didn't hurt the player??

I'm out of tries... help? I am reducing their hp every time they hit the wall am i not? considering the grid is 9X9 (smallest at 0 and largest at 9)

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
    if (x==0 and dx<0) or ( x==9 and dx>0) or (y==0 and dy<0) or (y==0 and dy>0):
        hp=hp-5
    else:
        x+=dx
        y+=dy

    return x, y, hp

This is the question:

Our game's player only has two attributes, x and y coordinates. Let's practice with a slightly different one, though. This one has x, y, and "hp", which stands for hit points. Our move function takes this three-part tuple player and 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). Finish the function so that if the player is being run into a wall, their hp is reduced by 5. Don't let them go past the wall. Consider the grid to be 0-9 in both directions. Don't worry about keeping their hp above 0 either.

It looks like you didn't specify all the conditions properly. You have two tests for when "y" is zero.

Instead of "(y==0 and dy>0)", perhaps you meant "(y==9 and dy>0)"?
