Quick Check: Python Descriptors and __set_name__

Review

1. Which statement best describes a descriptor?

   A descriptor is an object defining descriptor-protocol methods such as __get__, __set__, or __delete__.
2. When Report.status is evaluated and status is a descriptor, what value is passed as the instance argument to __get__?

   For class binding, the descriptor's __get__ receives None as instance and the class as owner.
3. When is __set_name__ called automatically?

   Python calls __set_name__ during class creation for class attributes whose objects define that hook.
4. Which object wins when a data descriptor and an instance dictionary both contain the same attribute name?

   Data descriptors take precedence over a same-named value in an instance dictionary.
5. Why can an instance override a non-data descriptor?

   A descriptor with __get__ but neither __set__ nor __delete__ is non-data, so an instance attribute can override it.
