Coding the dice and getting the players to move using coordinates and turtle

I am trying to code a snakes and ladders game using the turtle library. The position of each player has been defined using coordinates. Now I have some trouble coding the dice and getting the players to move accordingly.

Here is the bit of code I need help with:

def dice():

    turtle.addshape("bull.gif")

    player1 = turtle.Turtle()
    player1.shape("bull.gif")
    player1.penup()
    player1.goto(-240, -260)


    

    dice1 = random.randint(1, 6)

    #dice2 = random.randint(1, 6)



    player1_dice = input("\nBULL (P1): Please press 'ENTER' to roll the dice ")


    if player1_dice == "":
        print("BULL (P1) rolled a", dice1)

    elif player1_dice != "":
         print("BULL (P1): Please make sure to press 'ENTER' ")



    P1_coor =

    
    P1_pos = 1
    dieValue = dice1
    pos = 0

    for pos in range(dieValue):
        newPos = pos + P1_pos + 1
        player1.goto(newPos)

    P1_pos = newPos


        
dice()
