Example

Tkinter module

This example opens a blank desktop window. The tkinter module is part of the standard library.
To use tkinter, import the tkinter module.

1
from tkinter import *

This is tkinter with underscore t, it has been renamed in Python 3.

Setup the window

Start tk and create a window.

root = Tk()
app = Window(root)

The window class is not standard, we create a Window. This class in itself is pretty basic.
