好...，所以我在堆栈溢出和其他网站上看到了多篇帖子，主题相同。但是，给出的“解决方案”均无效。我见过类似的东西：
button.config(text="changed")
AND
button.configure(text="changed")
AND
button.deposit(text="changed") #I had a feeling it wouldn't work but still
我希望有人可以尝试找出我在做什么的问题，因为其他人可能也有同样的问题，也找不到答案 对于前2个解决方案，我遇到的错误是：
AttributeError：“ NoneType”对象没有属性“ configure”
AttributeError：“ NoneType”对象没有属性“ config”
我的代码如下（错误在第25行：
