井字游戏Python 2.7

Question

我正在做一个井字游戏程序，由于某些原因，当我试图打印一个3x3的板时，它不起作用。我得打印一块4x4板。程序的工作方式是，我们先输入一行，然后输入一列，然后在这些坐标处打印X或O，但就像我说的。。。它不适合3x3板。每当我输入第3行或第3列时，它会说坐标超出范围。。。任何帮助都将不胜感激。谢谢您。在

Answer 1

我试过把第二行改成：

rows,cols = 3,3

我在Python2.7解释器中做了这个，没问题！您忘了Python使用索引0、1和2而不是1、2和3吗？在

使用0代替1 用1代替2 用2代替3

你可以尝试让它使游戏使用1，2和3，使它更加用户友好，祝你好运！：）

Answer 2

您应该使用小于您作为索引输入的值，因为在python和其他大多数语言中，索引从0开始

设置

row,cols=3,3

而在getMove()函数中，则使用此函数

row = readInt("  Row  > ")-1
col = readInt("  Col  > ")-1

Answer 3

当为行或列输入3时，将调用

isOnBoard(board, 3, 3)

哪个叫

^{pr2}$

它将行设置为3

导致

(row < rows)

求值为假

您希望减少行和列，以符合Python基于零的索引
