In this recipe, we will create widgets for our Python GUI by using the factory design pattern. In the previous recipes, we created our widgets either manually one at a time or dynamically in a loop. Using the factory design pattern, we will use the factory to create our widgets.
Towards the top of our Python GUI module, just below the import statements, we create several classes:

from tkinter import ttk
