如何使用grid_remove将处于活动状态的忘记的小部件重新放置到网格中？

Question

我有以下代码：
一种。那里有两个单选按钮。
b。单击一个按钮，然后使用grid_remove()删除另一个单选按钮。
C。然后添加标签和输入小部件。
d。然后，我尝试执行dictionary['element'].grid()来取回已删除的小部件，但我看不到它再次放回原处。

        self.scl2.grid(row=8)

    self.entries['self.cv_button'].grid() #Calling the grid back is not getting placed back again.

def complecomponent(self):

    app.title("Test App")
    app.mainloop()

查询：
一种。不会调用grid（）来使用grid_remove（）取回已删除的小部件吗？
b。还是有更好的解决方案来收回小部件？

任何人都可以评论/建议需要做什么吗？
