[Tkinter] Update value in Entry widget

[dannyH]

I'm very new to tkinter. How do I get a value to display every time it changes? The code below only shows the last entry in the Entry widget, but print shows all the values (python 3.6.0)

from tkinter import *
def start():
    for n in range(1000000):
        if n%100000 == 0:
            v.set(str(n))
def makeWindow () :
    global v
    win = Tk()
    frame1 = Frame(win)
    frame1.pack()
    Label(frame1, text="Number").grid(row=0, column=0, sticky=W)
    v = StringVar()
    m = Label(frame1, textvariable=v)
    m.grid(row=0, column=1, sticky=W)
    frame2 = Frame(win)
    frame2.pack()
    b1 = Button(frame2,text=" Start  ",command=start)
    b1.pack(side=LEFT)
    return win
win = makeWindow()
win.mainloop()
