Set Name Method of the Descriptor Protocol
Explore how the __set_name__ method in Python descriptors allows automatic capture of attribute names, reducing redundancy and improving code clarity. Understand its role in managing descriptor attributes and maintaining flexibility in Python 3.6 and later.
Signature of the __set_name__ method
This is a relatively new method that was added in Python 3.6, and it has this structure:
__set_name__(self, owner, name)
When we create the descriptor object in the class that is going to use it, we generally need the descriptor to know the name of the attribute it is going to be handling. This attribute name is the one we use to read from and write to __dict__ in the __ get__ and __set__ ...
