python-3.9 - 在第 4 , 113 , 130 行制作井字游戏时输入错误

问题描述

我正在尝试制作井字游戏，但出现这些错误，我不知道为什么会出现这些错误。我检查了所有内容，但找不到任何东西。这就是我帮助你的原因。请告诉我发生这种情况的原因如果你知道的话。我会为此感谢你的。

在此处输入代码

    Exception has occurred: TypeError
    list indices must be integers or slices, not NoneType
    line 4, in insertLetter
    board[pos] = letter
    line 113, in main
    insertLetter('O' , move)
    line 130, in <module>
    main()

这些是行中的错误，下面是我为这个程序编写的代码。请帮助我。
