Question

我需要绘制我的x和o，这样当我点击一个正方形时，它会将它绘制在中间。我听说你可以找到广场的中点，但我也不知道怎么做。当我点击它们时，我能做些什么才能让X和O在正方形的中间画出来？

import turtle



#I need to fix the positions of the X and O's so that they draw more perfectly into the        squares of the board.



class TicTacToe:
    def __init__(self):
        self.u__init_board = []

Answer 1

由于您知道用户点击的X和Y坐标，因此您可以使用此信息来获取他们在哪个方格点击。
您可以使用坐标上的除法来识别单击了哪个方格，然后乘以将乌龟放置在该方格的中心。
要开始，请考虑每个方块的大小。

Tic Tac Toe X和O's
