The way I would do it is as follows:

   try:
       import tkinter as tk
       from tkinter import ttk
   except ImportError:
       import Tkinter as tk
       import ttk

If I may suggest, just write it in Python3 first, then when it does
what you want tack on whatever you need to make 2.7 happy.  I find it
easier to do things that way, though you may find that the only thing
you have to adjust is the imports.
