我是python和tkinter的新手，每当我尝试为我的程序添加自定义网格大小时，我就会收到以下错误。我非常确定这不是所有其他线程中的重复线程，它们都不涉及网格或在其问题中使用网格功能。
TypeError：/：＆＃39; int＆＃39;不支持的操作数类型和＆＃39; str＆＃39;制作网格时
每当我尝试在GUI中更改GridSize的值时，就会出现错误。您可以在＆＃39;更改寻宝游戏的设置中更改它的值。菜单的一部分。我是python的新手，所以请用最简单的术语来表达它！

请继续处理您的程序，但请使用以下代码替换您的代码并从那里开始工作。您可能还希望通过PEP8 online网站运行代码。对您的代码所做的更改包括确保没有生成错误或警告。
要回答您的问题，下面的两个功能与您的代码最初的功能略有不同。请注意前两个函数get_rows和get_columns。从Spinbox获取信息时，您需要在使用之前将数据转换为正确的类型。
