Python 在Tkinter中使用背景图像后按钮错位

每当我使用背景图像运行此代码时，按钮网格就会放错位置并被推向底部。幸运的是，当没有添加背景时，它可以正常工作。我希望它们在执行时覆盖背景。下面添加了供参考的图片。非常感谢你的帮助

第一个图像是错误。第二个图像是所需的输出。 注意：我还是Python和Tkinter的初学者，因此各种术语和方法可能超出了我的范围。如能考虑，将不胜感激

如果需要，您可能知道这是一个tkinter项目，用于从*a网格中挑选奇数图像。

我自己得到了答案，因此将分享以备将来使用

C = Canvas(root, bg="blue", height=250, width=300)

此部件绘制250*300尺寸的画布，因此不允许按钮在其上绘制

把它改成

C = Canvas(root, bg="blue", height=0, width=0)

为了达到预期的效果
