>>> from Tkinter import *
>>> from ttk import *
so that those widgets replaced by ttk will be imported over the older ones in Tkinter.
I'm not going to include Tix because there are over 40 widgets that are added, but there are two important differences between Tix and ttk.
- Tix hasn't seen development since 2008 whereas ttk was last upgraded in 2012
- Tix isn't part of Tk/Tcl - it is a 3rd party add-on.

|ttk Progressbar widget|
So I think I'm going to stick with ttk imported on top of Tkinter as suggested by Python, and I'll only supplement these widgets with Tix if I absolutely must, since the ttk widgets really do seem better.
