我不知道如何定义cells，因为它是一个参数。

我发现你在make_move函数中引用了变量单元而没有声明，也许你应该在参数列表中定义它。顺便说一下，你必须提出你所有的追踪，或者我们所有人都很难找出问题所在。

回溯（最近通话最后一个）：文件 “C：\用户\管理员\桌面\新建文件夹\ a1_simple_check.py” 53行，在结果= tictactoe_functions.make_move（ 'X'，1， 1，' - '）文件“C：\ Users \ Administrator \ Desktop \新建文件夹\ tictactoe_functions.py”，第93行，在make_move中 size = len（cells）** 0.5 builtins.NameError：name'cells '未定义 –

您应该在make_move的参数列表中声明cells变量。 – hsfzxjy

你解决了这个问题吗？ – hsfzxjy

你有

def make_move(symbol,row_index,col_index,game_board):

下一次NO cells参数仔细阅读错误消息，这样你就知道在哪个行代码你有问题。
