井字游戏的if陈述问题

Question

我目前正在为Tic Tac Toe游戏编写脚本，但遇到了一个问题。当我的获胜声明起作用时，立即宣布一个玩家是否有一个，而我的平局却没有。当填充最后一个会导致平局的空插槽时，它的行为就好像它已经进行了普通移动一样，并且仅在后续移动中才声明平局。为了澄清起见，董事会是列表清单。我的代码如下。

class TicTacToe:
"""Defines a Tic Tac Toe game"""

def get_current_state(self):
    """Returns the current state of the Tic-Tac-Toe game"""
    return self._current_state

def __init__(self):
    """Initiates a new TicTacToe game with a board and current state"""
    self._board = [["", "", ""], ["", "", ""], ["", "", ""]]
    self._current_state = "UNFINISHED"

def make_move(self, row, column, player):
    """Places the users move on the board"""

    # Checks if any legal moves allowed and if so, places player on board
    if self._board[0][column] != player and self._board[1][column]\
            != player and self._board[2][column] != player or \
            self._board[row][0] != player and self._board[row][1] != player\
            and self._board[row][2] != player or self._board[0][0] != player\
            and self._board[1][1] != player and self._board[2][2] != player\
            or self._board[0][2] != player and self._board[2][0] != player\
            and self._board[1][1] != player and self._current_state == "UNFINISHED":

        self._board[row][column] = player


        # Checks for vertical wins and updates _current_state
        if self._board[0][column] == player and self._board[1][column] == player \
                and self._board[2][column] == player:
            self._current_state = player.upper() + "_WON"
            return True

        # Checks for horizontal wins and updates _current_state
        elif self._board[row][0] == player and self._board[row][1] == player \
                and self._board[row][2] == player:
            self._current_state = player.upper() + "_WON"
            return True

        # Checks for diagonal wins and updates _current_state
        elif self._board[0][0] == player and self._board[1][1] == player\
            and self._board[2][2] == player or self._board[0][2] == player\
                and self._board[2][0] == player and self._board[1][1] == player:
            self._current_state = player.upper() + "_WON"
            return True


        # Checks if the board is full with no wins and declares game a draw
        elif "" not in self._board and self._current_state == "UNFINISHED":
            self._current_state = "DRAW"
            return True

        return True

    else:
        return False

我在二维列表（在列表中称为列表）遇到了相同的问题。仅检查“”是否在整个开发板内部是行不通的，因为“开发板”列表中有很多列表。我建议编写代码以检查板上是否覆盖了每个瓷砖。
