Hmm, didn't get the right movement results.

I don't get it, it seems like a right answer when I run it on the workspace, but I am still missing something

# 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 == (1, 0):
        if x == 9:
            hp -= 5
            x += 1
    elif direction == (-1, 0):
        if x == 0:
            hp -= 5
            x = -1
    elif direction == (0, 1):
        if y == 9:
            hp -= 5
            y += 1
    elif direction == (0, -1):
        if y == 0:
            hp -= 5
            y -= 1
    return x, y, hp

Even though the examples show only movement of one unit in one direction, it's possible that the direction might be changed in both directions at once, or that the movement might be more than one unit at a time.

Try revising your strategy to accommodate both of these possibilities and I'll bet you'll pass. Give it a little thought, and you can also make the entire function more compact, too.

thanks, I really didn't think about that. I made it more universal and it worked
