Run this program. The radio buttons select the action taken when you click the GO button. Modify this code to suit your need.

import string

try:
    import tkinter
except:
    import Tkinter as tkinter

class c:

    def __init__(self):
        r = tkinter.Tk()
        B = tkinter.Button
        B(r,text='quit',command=r.destroy).pack(side=tkinter.BOTTOM)
        B(r,text='GO',command=self).pack(side=tkinter.BOTTOM)
        f = tkinter.Frame(r)
        f.pack(side=tkinter.BOTTOM)
        e = tkinter.Entry(r)
        e.pack(side=tkinter.BOTTOM)
        e.insert(0,'ExAmPlE')
        v = tkinter.IntVar()
        v.set(0)
        R = tkinter.Radiobutton
        R(f,text='lower',variable=v,value=0,font=("Helvetica","12")).pack(
            side=tkinter.LEFT)
        R(f,text='UPPER',variable=v,value=1,font=("Helvetica","16")).pack(
            side=tkinter.LEFT)
        self.root = r
        self.radio = v
        self.entry = e
        r.mainloop()

    def __call__(self):
        e = self.entry
        value = e.get()
        e.delete(0,tkinter.END)
        e.insert(0,(string.lower,string.upper,)[self.radio.get()](value))

if '__main__' == __name__:
    c()
