Set Method of the Descriptor Protocol
Explore the __set__ method within Python's descriptor protocol to understand how it controls attribute assignments. Learn how this method compares to property setters and how to use it for creating reusable, dynamic validation objects that improve code maintainability and clarity.
Signature of the __set__ method
The signature of this method is as follows:
__set__(self, instance, value)
This method is called when we try to assign something to a descriptor. It is activated with statements such as the one below, in which a descriptor is an object that implements __set__(). The instance parameter, in this case, would be client, and the value would be the "value" string:
client.descriptor = "value"
