There are many different Python modules available that let us create graphical programs, but we're going to use one called Tkinter. This module is included with Python by default and works on almost all computers and operating systems. It allows Python to communicate with the Tk toolkit, and it is Tk which will generate our displays.
Tkinter has easy-to-use functions to create textboxes, buttons, scroll bars, menus, and more. Collectively, these components are called widgets.
