First hit googling for 'tkinter center' is

http://www.daniweb.com/forums/thread66181.html

With minor stylistic changes this becomes:

from Tkinter import *
 
def center_window(w, h):
    # get screen width and height
    ws = root.winfo_screenwidth()
    hs = root.winfo_screenheight()
    # calculate position x, y
    x = (ws//2) - (w//2) 
    y = (hs//2) - (h//2)
    root.geometry('%dx%d+%d+%d' % (w, h, x, y))
 
root = Tk() 
center_window(500, 300) 
root.mainloop()

A good basic source for Tkinter programming is
