tkinters radiobutton's have an option 'indicatoron=0'  which should display Radio Buttons as actual labelled buttons.  

button = tk.Radiobutton(self, text=option, variable = var, value = answer, indicatoron=0)

Screenshots of expected and actual results ... http://imgur.com/a/2fI02

taken from ... http://stackoverflow.com/questions/34459221/tkinter-radiobutton-indicatoron-value-doesnt-effect-anything

Kkinter 8.5 descrbes the functionality as so : 
Normally a checkbutton displays as its indicator a box that shows whether the checkbutton is set or not. You can get this behavior by setting indic- atoron=1. However, if you set indicatoron=0, the indicator disappears, and the entire widget becomes a push-push button that looks raised when it is cleared and sunken when it is set. You may want to increase the bor- derwidth value to make it easier to see the state of such a control.

Works to me on Linux (identical results with Tkinter and Tk). In any case if there is some bug on your platform, this is not Tkinter bug, but Tk bug. Tkinter doesn't handle this option specially, it just pass it to Tk. File a bug on Tk bugtracker: http://core.tcl.tk/tk/ticket .

Thank you

FYI, it seems that the Tk team are unable to use cocoa for this
functionality so indicatoron has not worked on OSX for Radiobuttons or
Checkbuttons for over 4 years.
