我的 tic tac toe python 游戏有问题

Question

问题是在显示获胜者之后，它并没有摆脱循环。它要求玩家说出他想把 X 放在哪里。如果你们能帮助我，我将非常感激。 我想让它开始游戏。可玩回合制，当有人获胜时会显示获胜者并询问他们是否想再次玩

Answer 1

这里有很多代码，但你遇到的是范围问题。我会将其缩小，以便您可以清楚地看到问题。考虑这段代码：

def outer_function():
    GG = False

    def inner_function():
        GG = True

    print(GG)

outer_function()

它将打印

False

，因为

GG = True

没有在外部函数中将

GG

设置为

True

，它会隐藏它。

相反，尝试

return

设置一个值：

def outer_function():
    GG = False

    def inner_function():
        return True

    GG = inner_function()
    print(GG)

outer_function()

因此，如果有获胜者，

check_for_winner

应返回

True

，如果没有获胜者，则应返回

False

。当你调用这个函数时，写：

GG = check_for_winner()
