这篇blog主要是描述python中tkinter的单选按钮操作
下面是我做的demo
运行效果:

3 # This is a demo program that shows how to
4 # create radio buttons and how to get other widgets to
5 # share the information in a radio button.
6 #
7 # There are other ways of doing this too, but
8 # the "variable" option of radiobuttons seems to be the easiest.
9 #
10 # note how each button has a value it sets the variable to as it gets hit.
