Just bouncing a red ball within the frame of a window, the twist here is that the image is stored within the code as a base64 encoded string of the gif image. This way you only have to distribute one file. The Python code is heavily commented, so you can …

The normal XOR crypting is used with a small base64 twist to produce printable crypted text.

This shows you how to draw a colorful bar graph of a data set using the Tkinter canvas and rectangles. An attempt has been made to use most of the canvas area for the graph. The bars are spaced and labeled with the corresponding value. The x-axis is simply the …

Small image files can be embedded in Python code using the base64 encoded string of the image. If you have to present a number of small fixed images in your program, embedding might be easier than including a set of image files. Attached files can be lost, and than your …

This code shows you how to build a multiline story string that should display similarly to way it shows in the code. It should be relatively easy to maintain.

VPython's fame is with 3D animated modeling, but it's plotting abilities, while not flashy, are easy to understand and very useful. This program uses VPython to plot math functions y = sin(x) and y = cos(x) and y = sin(x)*cos(x).

If you have a Windows computer you can play musical beeps through the internal speaker. In this case it will sound like a very tiny Big Ben, brought to you by the module winsound and its method Beep().
