Thank you to everyone who made suggestions of a definition of a property. I
will go with a definition based on this one from Jon R, with the clarification
from Terry R.
Yes, the upcoming book is on object-oriented programing using Python, and goes
into detail about the concepts behind OOP. The unique approach is that I use
pygame and explain how to build a number of user interface "widgets" (like
buttons, text input and output boxes, draggers, etc.) to show the fundamentals
of OOP in a highly visible way. I use these widgets to implement a number of
small games that also incorporate some additional classes like timers,
animation, etc.
