您的代码无法快速修复。它试图成为面向对象的，但这样做是不正确的。您需要正确定义您的方法，还应遵守 PEP8 命名约定——具体来说，方法和函数应以小写字母开头，而 类 应以大写字母开头。因为您不遵循 PEP8，并且由于您使用 Prime_Gen 在不同时间表示不同事物的奇怪方式，您的代码难以理解。
问题的症结在于OnGenButtonClick里面，Prime_Gen并不是你想的那样。它是 Prime_app_tk 的一个实例，而不是您在 Prime_Gen_Win 中设置局部变量 Prime_Gen 的值。因此，您分配给原始 Prime_Gen 的任何属性在另一个 Prime_Gen 中都不存在。
原因是按钮是这样定义的：
Genbutton = Button(..., command=self.OnGenButtonClick, ...)
在此上下文中，self 是 Prime_app_tk 的实例，因此它成为传递给 OnGenButtonClick 的参数。在该函数中，您调用参数 Prime_Gen，尽管通用约定将其命名为 self。这会导致代码混乱，因为在创建顶层 window.
的代码中还有一个名为 Prime_Gen 的局部变量
这是我的代码，当我尝试 运行 它并通过在输入字段中输入数字来使用它时，当我尝试调用输入变量时发生属性错误。这是出现的消息：

您的代码无法快速修复。它试图成为面向对象的，但这样做是不正确的。您需要正确定义您的方法，还应遵守 PEP8 命名约定——具体来说，方法和函数应以小写字母开头，而 类 应以大写字母开头。因为您不遵循 PEP8，并且由于您使用 Prime_Gen 在不同时间表示不同事物的奇怪方式，您的代码难以理解。
问题的症结在于OnGenButtonClick里面，Prime_Gen并不是你想的那样。它是 Prime_app_tk 的一个实例，而不是您在 Prime_Gen_Win 中设置局部变量 Prime_Gen 的值。因此，您分配给原始 Prime_Gen 的任何属性在另一个 Prime_Gen 中都不存在。
原因是按钮是这样定义的：
Genbutton = Button(..., command=self.OnGenButtonClick, ...)
在此上下文中，self 是 Prime_app_tk 的实例，因此它成为传递给 OnGenButtonClick 的参数。在该函数中，您调用参数 Prime_Gen，尽管通用约定将其命名为 self。这会导致代码混乱，因为在创建顶层 window.
