The last two Simple Tricks posts looked at subclasses of built-in Python classes, in particular the tuple class, as well as the built-in class methods Python supports for any user-defined class. [See Simple Tricks #10 and Simple Tricks #11.]
This time I narrow the focus to real and virtual object attributes, the “x”, “y”, “z” elements of our vector objects. Python offers many ways to implement these, depending (as always) on what you want.

Python has the useful notion of descriptor objects, which give object attributes control over how they are accessed. Descriptors enable calculated-on-the-fly attribute values and can prevent or control modification of data values.
The previous post covered the basics. In this post, I’ll dig deeper into Python descriptors with some more involved examples. This post assumes the basics covered in the previous post.

Python has the useful notion of descriptor objects as well as the built-in property() function to make using them in the most common cases — read-only and calculated instance attributes — quite easy.
In this post I’ll explore Python descriptors with lots of examples demonstrating how to use them. Descriptors are an important aspect in understanding Python and using it effectively.
