AttributeError:类框架没有属性“StringVar”

Question

所以我有下面的代码。我尝试了各种各样的方式来使用StringVar，但是什么也没发生。这就是为什么a转向你哦，上帝啊。请告诉我怎么通过。我在Entry1中有一个输入，我需要把这个输入输入到一个sql中（因为它不重要，我把它删掉了），然后返回它的值，并把它写进Entry1而不是原来的输入。我的主，所以请停下来！你知道吗

更新

我必须这样改变：

    def callback(self): 
        #07561847   
        #tk()
        atvevoText = StringVar()
        number = self.entry1.get()
        self.entry1.delete(0, 'end')
        #self.entry1.insert(0, atvevoText)
        self.entry1 = Entry(self, textvariable = atvevoText )
        atvevoText = atvevo(number)             
        print(atvevoText)

*有了它，我没有什么可支持的，也没有错误，也没有价值：（*

Answer 1

改变

Frame.StringVar()

至

StringVar()

因为StringVar是Tkinter中的一个类（不只是google测试）
