Can i get some help here please?

so... i'm stuck here since yesterday and i can't figure it out what to put inside the if block... i guess i should sum x and y from player argument.... can you help me out?

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)

import operator

limit = [(0, 0), (1, 0), (2, 0), (3, 0), (4, 0), (5, 0), (6, 0), (7, 0), (8, 0),
         (0, 1), (1, 1), (2, 1), (3, 1), (4, 1), (5, 1), (6, 1), (7, 1), (8, 1),

def move(player, direction):
    x, y, hp = player

    if player in limit:
        tuple(map(operator.add, player, direction))
    if player not in limit:
        print("it's not a valid command")
        hp -= 5

    return x, y, hp

I couldn't update the question, so i'm posting the challenge here...

Challenge Task 1 of 1

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.

You haven't changed the original x, y coordinates.

x1, y1 = direction
# change x, y values according to direction 
x, y = x + x1, y + y1

Then

    if x > 9:
        hp -= 5
        x -= 1
    elif x < 0:
        hp -= 5
        x += 1

Do the same for y-value and return x, y, hp

Here is my solution as an example:

def move(player, direction):
    x, y, hp = player
    x_move, y_move = direction
    # here we change x, y according to direction
    x, y = x + x_move, y + y_move
    # then we check if x or y is some invalid integer
    if x > 9:
        # if it is an invalid integer, like 10 or -1, we remove 5 health points and return the player to a valid integer
        # in this cases, x is greater than 9, ie 10. Therefore, we remove 5 hp and make x = 9
        hp -= 5
        x -= 1
    elif x < 0:
        hp -= 5
        x += 1
    elif y > 9:
        hp -= 5
        y -= 1
    elif y < 0:
        hp -= 5
        y += 1

right answer is here

def move(player, direction):
    x, y, hp = player
    a,b = direction
    x += a
    y += b
    if x not in range(10):
        x -= a
        y -= b
        hp -= 5
    elif y not in range(10):
        x -= a
        y -= b
        hp -= 5
    return x, y, hp
def move(player, direction):
    x, y, hp = player
    dx, dy= direction
    if dx !=0:
        x+=dx
        if x not in range(10):
            hp-=5
            x-=dx
    if dy !=0:
        y+=dy
        if y not in range(10):
            hp-=5
            y-=dy
    return x, y, hp
