As mentioned earlier, a GUI provides a way to interact with an application. Instead of a text-based input, the user is presented with elements such as text boxes, radio buttons, tool bars, and so on. This section will introduce you to the basics of GUI programming with Tkinter. This library is available as a standard module in Python.
Let's document some links for a handy reference. The official Tkinter documentation page can be found at https://docs.python.org/3/library/tkinter.html#module-tkinter. This page lists several external references. A good introduction is available at http://effbot.org/tkinterbook. Of course, you can always perform a web search with search terms like python and Tkinter to find more resources.
Alternatively, you can quickly find the supported functionality and documentation using the Python interpreter!
>>> import tkinter >>> dir(tkinter)
The preceding command lists the supported classes, functions...
