How do I read the radio button value without clicking in tkinter python

What is the best way to read a radio button when it is already selected in tkinter Python.

I have a function in main loop, Radio button is used to call other functions, this process is run in While1: loop, problem is I have to select the radio button in each time of processing. is there any method to select the earlier selected radio button value, unless radio button is not changed.

You should use mainloop instead of a infinite while loop.
Here is an example that prints the value of the selected radiobutton, every second:

from tkinter import *


def read_value(e):
    print(v.get())
    master.after(1000, read_value, 'dummy')


master = Tk()

v = IntVar()
v.set(1)

r1 = Radiobutton(master, text="One", variable=v, value=1)
r1.pack(anchor=W)
r2 = Radiobutton(master, text="Two", variable=v, value=2)
r2.pack(anchor=W)

read_value('dummy')

master.mainloop()
