Tic-Tac-Toe游戏

Question

我为Tic-Tac-Toe游戏编写了一个代码。

以下是代码的作用：

1. 获取播放器1的名称。
2. 获取播放器2的名称。
3. 询问玩家1是否需要X或O。
4. 如果他选择X，则玩家2获得O，反之亦然。
5. 打印空白板。
6. 要求两位玩家逐个输入行和列并打印更新后的电路板。
   • 如果玩家没有重复上一个玩家的位置，一切正常，直到结束没有任何问题。
   • 如果玩家重复上一个玩家的位置，会显示一条消息，说明之前的玩家已经占据了这个位置并让他再次猜测。

现在，在此之后，如果我猜测除了前一个玩家已经采取的指数以外的任何指数，它将覆盖之前的玩家现货。

发生这种情况时终端的屏幕截图：



我确定问题出在函数enterguess(turncount)中，但还没有能够发现它。知道问题在哪里吗？

您遇到的问题是，虽然您记得enterguess，但您不会将其退回。所以它只是一直调用enterguess直到给出一个有效的输入，然后它就会忽略所有这些并转到最终的返回语句，它仍然有错误的猜测。

添加return语句：

def enterguess(turncount):
    def guess(name):
        return (int(input("\n" + players[name] + ", Enter row number: ")),
                int(input(players[name] + ", Enter column number: ")))

    if turncount % 2 == 0:
        (row, col) = guess('player1')

        try:
            if board[row - 1][col - 1] in [sym['player1'], sym['player2']]:
                print "\n" + players['player2'] + " already took that spot! Please guess again."
                return enterguess(turncount)
        except:
            print "\nPlease enter the indexes between 1 and 3."
            return enterguess(turncount)

    else:
        (row, col) = guess('player2')

        try:
            if board[row - 1][col - 1] in [sym['player1'], sym['player2']]:
                print "\n" + players['player1'] + " already took that spot! Please guess again."
                return enterguess(turncount)
        except IndexError:
            print "\nPlease enter a number between 1 and 3."
            return nterguess(turncount)

    return (row - 1, col - 1)
