Can someone help me with this python tuples challenge?

I honestly don't understand why this code doesn't work. Following was 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.

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
    x_direct, y_direct = direction
    x_result = x+x_direct
    y_result = y+y_direct
    if x_result<=-1 or x_result >= 10 or y_result>=10 or y_result <= -1:
        hp -= 5
    else:
        x += x_direct
        y += y_direct
    return x, y, hp

Your code looks good to me. :+1:

So I tried pasting it directly into the challenge, and it passed!

I've heard that sometimes restarting the browser can help, give that a try and the re-enter your solution.
