在我的程序中，我在第2帧中分别使用了4个单选按钮和两个按钮。但我想在（0,0）位置显示r1＆amp; r2，在（1,0）位置显示R3＆amp; r4纽扣。如果我使用＆＃34; grid＆＃34;方法没有以适当的方式显示。

我认为您可能会对如何使用grid()经理感到困惑。
查看代码的结果，我发现事情是错开的。我认为您正在更改row和列`，而不仅仅是更改其中一个。
当您在窗口小部件上使用网格管理器时，网格放置仅与其所在的框架相关。您也可以在框架上使用相同的网格管理器。通过这种方式，您可以决定帧的去向，而不用担心帧的创建顺序。
当我们从不同的小部件中定义了3列和3行时，下面表示使用网格布局的框架。
在每个框中，您将看到在为该窗口小部件分配网格时每个窗口小部件的放置位置。请记住，如果每行/每列中至少有一个小部件，则下面只会保持其形状。如果不是，框架将自动调整大小以适合其内容。
因此，例如，如果我们将小部件放在（0,0），（1,1）和（2,2），那么框架将保持其3x3布局。如果我们只将小部件放在（0,1），（0,2）和说（1,2）中，那么框架现在只有2x2网格。

请注意，有很多工具可以通过使用锚点和粘性来获得更精确的展示位置。 grid()经理是Tkinter中3位不同几何经理的最爱，但他们都有自己的用途。
以下是代码的简化版，以便更好地说明grid()经理如何设置小部件的格式。
