Python 使用pack_忘记帧消失

我已经创建了一个主窗口，当单击B1按钮时，应使用object.place\u forget、object.pack\u forget删除框架，以便稍后创建一个新窗口。但我收到了错误消息

文件“/trial.py”，第60行，在设置中 self.Data\u frame.pack\u忘记（） AttributeError:Gui实例没有“Data\u frame”属性

大写

F

，

数据帧

非

数据帧

。您在

Info\u框架中也缺少
I
，并且您没有调用以下方法：

    def setup(self):
        self.Data_Frame.pack_forget()
        self.Data_Frame.place_forget()
        self.Info_frame.place_forget() # call
        self.Info_frame.pack_forget() #  self.Info_frame not  self.nfo_frame

如果您进行了这些更改，一切都会正常工作。
您一直在使用
self.Data\u Frame
和以后的
self.Data\u Frame
。Python名称区分大小写。您没有问任何问题。你需要什么帮助？
