Python descriptors are a way to create managed attributes.

Python descriptor protocol is simply a way to specify what happens when an attribute is referenced on a model. It allows a programmer to easily and efficiently manage attribute access:

• set
• get
• delete

Managed attributes are used to protect an attribute from changes or to automatically update the values of a dependant attribute.

We can create a descriptor in a number of ways like:

• using class methods
• using property type
• using property decorators
