What happens when some buttons have same value

from Tkinter import * 
     
root = Tk()
var = StringVar()

for i in range(10):
    rad = Radiobutton(root, text=str(i), variable=var, value=str(i % 3))
    rad.pack(side=LEFT)

root.mainloop()

fruit=[('Option 1', 1), ('Option 2', 2), ('Option 3', 3),
       ('Option 4', 4), ('Option 5', 5), ('Option 6', 6)]
var = IntVar()
for text, value in fruit:

Radio button bar: get selected button for a group radio button

from Tkinter import *

class Radiobar(Frame):
    def __init__(self, parent=None, picks=[], side=LEFT, anchor=W):
        Frame.__init__(self, parent)
        self.var = StringVar()

            rad = Radiobutton(self, text=pick, value=pick, variable=self.var)
            rad.pack(side=side, anchor=anchor, expand=YES)
    def state(self):
        return self.var.get()


class Quitter(Frame):                      
    def __init__(self, parent=None):         
        Frame.__init__(self, parent)
        self.pack()
        widget = Button(self, text='Quit', command=self.quit)

        if ans: Frame.quit(self)


if __name__ == '__main__':
    root = Tk()
    gui = Radiobar(root, ['A', 'B', 'C'], side=TOP, anchor=NW)
    gui.pack(side=LEFT, fill=Y)
    gui.config(relief=RIDGE,  bd=2)

    def allstates(): print gui.state() 
    Quitter(root).pack(side=RIGHT)
    Button(root, text='Peek', command=allstates).pack(side=RIGHT)
    root.mainloop()

Get Radio button state

from Tkinter import *      

root = Tk()           

var  = IntVar()       

for i in range(10):
    rad = Radiobutton(root, text=str(i), value=i, variable=var)
    rad.pack(side=LEFT)

root.mainloop()
print var.get() 

Hold on to your radio variables

from Tkinter import *      
root = Tk()                   

def radio1():                   
    tmp = IntVar()
    for i in range(10): 
        rad = Radiobutton(root, text=str(i), value=i, variable=tmp)
        rad.pack(side=LEFT)
    tmp.set(5)    

radio1()
root.mainloop()

Save Radio button states

from Tkinter import *      
state = ''
buttons = []

def onPress(i):
    global state
    state = i
    for btn in buttons:
        btn.deselect()
    buttons[i].select()

root = Tk()
for i in range(10):
    rad = Radiobutton(root, 
                      text=str(i), 
                      value=str(i), 
                      command=(lambda i=i: onPress(i)) )
    rad.pack(side=LEFT)
    buttons.append(rad)
root.mainloop()

print state
