获取画布的高度创建窗口对象python tkin

Question

我有一个程序，几乎所有的东西都放在画布上，用框架之类的东西：`

canvas = Canvas(root,width = 800, height = 800) 
frame = Frame(root)
window = canvas.create_window(10, 10, anchor = "nw", window = frame)

框架里还有一些小部件。我的问题是，当print (canvas.bbox(window)返回(10, 115, 11, 116)并且坐标是10115时，如何获得canvas.create_window的宽度和高度？谢谢
