Hey guys this is my second attempt at a Tic Tac Toe game using the advice given in my first post: My first Python project: Tic Tac Toe

Again, just looking for advice on things I can improve. There is no classes because I have not really learned a great deal about OOP yet. I wanted to make sure I could use functions proficiently before I continued. I'm sure there is a way to loop the win_check(), but I have not figured it out yet.

def num_to_coord(num):

# 0-index num

    num -= 1

    coord = 

    while True:

        curr_coord = num % 3

        coord.append(curr_coord)

        if len(coord) >= 2:

            break

        num -= curr_coord

        num //= 3

    return coord





def change_symbol(the_symbol):

    if the_symbol == 'x':

        the_symbol = 'o'

        return the_symbol

    if the_symbol == 'o':

        the_symbol = 'x'

        return the_symbol





def get_position():

    position = int(input("Enter a position: "))

    return position





def check_position(the_position, the_taken_positions):

    if the_position in the_taken_positions:

        return True

    if the_position not in the_taken_positions:

        return False





def draw_position(location, the_symbol, the_game_board):

    coord = num_to_coord(location)

    the_game_board[coord[0]][coord[1]] = the_symbol

    for y in range(3):

        print(add_sep('|', [the_game_board[x][y] for x in range(3)]))
