Maybe it's just personal opinion, but I do think there are scenarios 
where it makes sense to have no radio buttons selected.

But, anyways...  I did something related that will work for now - create 
a third button, but keep it hidden with .Hide().  In case anyone's 
interested, the example I included before is changed as below, and does 
basically what I want.



#!/usr/bin/python
import wx
app = wx.PySimpleApp()
frame = wx.Frame(None,-1,"TESTING")

def go(ev):
     print rb1.GetValue(), rb2.GetValue(), rb3.GetValue()
     rb3.SetValue(True)
     print rb1.GetValue(), rb2.GetValue(), rb3.GetValue()

p = wx.Panel(frame,-1)
rb1 = wx.RadioButton(p,-1,"A")
rb2 = wx.RadioButton(p,-1,"B")
rb3 = wx.RadioButton(p,-1,"C")

ID_BUTTON = 201
b = wx.Button(p, ID_BUTTON, "GO")
wx.EVT_BUTTON(p, ID_BUTTON, go)

sizer = wx.BoxSizer(wx.HORIZONTAL)
sizer.Add(rb1,1,wx.EXPAND)
sizer.Add(rb2,1,wx.EXPAND)
sizer.Add(rb3,1,wx.EXPAND)
sizer.Add(b,1,wx.EXPAND)

p.SetSizer(sizer)

frame.Show(1)
rb3.Hide()
app.MainLoop()
