Descriptors are not black magic and this practical tutorial will show you that. In fact, you use descriptors every day and you don't even know it!

Through a series of practical, hands-on exercises, you will learn

• how to create a descriptor;
• how to use the dunder methods __get__, __set__, and __set_name__;
• what the descriptor protocol is; and
• where descriptors show up in day-to-day Python code.

The expected Python level for participants is “intermediate”. In practice, if you are comfortable with using the built-in property and if you have used dunder methods before, you should be fine.

This tutorial is based off of an article I wrote about descriptors.
