Python Tic-tac-toe博弈逻辑问题

[已编辑] 为了简单起见，我将在这里包括整个文件：

choices = ['1', '2', '3', '4', '5', '6', '7', '8', '9']
Is_Current_One = True
won = False
wrongEntryPlayer1 = False
wrongEntryPlayer2 = False
while not won:

        print('\n')
        print('|' + choices[0] + '|' + choices[1] + '|' + choices[2] + '|')
        print('----------')
        print('|' + choices[3] + '|' + choices[4] + '|' + choices[5] + '|')
        print('----------')
        print('|' + choices[6] + '|' + choices[7] + '|' + choices[8] + '|')
    # above code is to print board layouts
    if Is_Current_One:
        print("Player 1's turn.\nChoose a number to put an X there.")
        try:
            choice = int(input("> ").strip())
            wrongEntryPlayer1 = False
        except ValueError:
            print("Please enter only valid fields from board (0-8)")
            wrongEntryPlayer1 = True
            continue
    else:
        print("Player 2's turn.\nChoose a number to put an O there.")
        try:
            choice = int(input("> ").strip())
            wrongEntryPlayer2 = False
        except ValueError:

            wrongEntryPlayer2 = True
            continue

    if Is_Current_One:
        if choices[choice - 1] == int:
            try:
                choices[choice - 1] = 'X'
                wrongEntryPlayer1 = False
            except IndexError:

    else:

            try:
                choices[choice - 1] = 'O'
                wrongEntryPlayer2 = False
            except IndexError:
                print("Please enter only valid fields from board (0-8)")
                wrongEntryPlayer2 = True
        else:
            print("Please choose a number that is empty.")
            wrongEntryPlayer2 = True
    # code to toggle between True and False
    Is_Current_One = not Is_Current_One

    for pos_x in range(0, 3):
        pos_y = pos_x * 3

        # for row condition:
        if (choices[pos_y] == choices[(pos_y + 1)]) and (
                choices[pos_y] == choices[(pos_y + 2)]):
            won = True

        # column condition:
        if (choices[pos_x] == choices[(pos_x + 3)]) and (
                choices[pos_x] == choices[(pos_x + 6)]):
            won = True
    if ((choices[0] == choices[4] and choices[0] == choices[8])
            or (choices[2] == choices[4] and choices[4] == choices[6])):
        won = True

print("Player " + str(int(Is_Current_One + 1)) + " won, Congratulations!")

如果你真的读了代码，你会发现我正在做一个井字游戏。 我声明了两个布尔变量：

ErrorEntryPlayer1

和

ErrorEntryPlayer2

，这两个变量最初默认设置为

False

，因为游戏刚刚开始。 在玩这个游戏时，玩家需要输入一个整数，这个整数在游戏板上显示，在那里放置一个

X

或

O

。 如果玩家没有输入整数，程序就会崩溃，我不希望这样。相反，我使用了

try

语句，在他们没有输入整数时打印一条用户友好的消息。 发生这种情况时，我不希望Python再次打印游戏板，因此当玩家输入错误的值时，我将相应的ErrorEntryPlayer变量设置为True。这样，如果任何一个玩家输入了错误的值，我将完全跳过打印游戏板

然而，当我试着运行它时，在第一个回合输入了错误的值，然后输入了正确的值，游戏板仍然不会出现。即使轮到玩家2，游戏板仍然没有打印

当玩家输入正确的值（整数）时，游戏板仍然不会显示

此外，当玩家输入已被另一玩家占用的值时，程序应提示玩家再次输入。相反，它只是跳过了玩家的回合

我是python初学者，所以有些代码可能看起来很傻。有人能帮我解释一下如何解决这个问题吗？谢谢 多亏了Sanetro，我原来的问题得到了解决。现在又发生了另一个错误。详细问题发布在Sanetro回答的评论部分。我在这里包括我的详细编辑代码

[编辑2] 好的，Sanetro，这实际上是最后一次编辑。 我正在做一个退出命令。当播放机键入>退出时，程序退出。我本来以为这会很简单。你做了一个while循环，当玩家退出时打破循环，就这样！嗯，这并不简单（至少对我来说）。由于choice=input（…）在循环中，因此我不能将其置于循环之外（或在声明choice变量之前），这是不好的。我在顶部创建了一个新变量：exitTrigger，并在while循环中添加了新行。现在它不起作用了。当播放器类型退出时，它只是说请只输入有效字段。这可能是因为except语句仍然有效，我想添加一个条件来触发except语句，并且当exitTrigger为True时，我只想使用except语句。我可以这样做吗？谢谢

 if not wrongEntryPlayer1 and not wrongEntryPlayer2:

你应使用：

这将解决印制电路板的部分问题。
我想不用

 if not wrongEntryPlayer1 and not wrongEntryPlayer2:

你应使用：

if wrongEntryPlayer1 or wrongEntryPlayer2:

这将修复印刷电路板的部分。
您的代码实际上有两个问题-首先，您请求帮助的问题是由于切换标志
是当前的\u One
而引起的，即使在播放器输入“错误”输入时也是如此。换句话说，当玩家一输入“asdf”时，我们希望他们有机会再次输入“良好”输入，而不是立即切换到玩家二。将
if
块放在该行上，该行显示
if not ErrorEntryPlayer1和not ErrorEntryPlayer2:

第二个更大的问题是你的类型检查玩家的输入是否为
int
无效。首先，
choices[choice-1]==int
将数组中的值与类型进行比较，
