Python.Descriptors

#+title: Python/Descriptors
Described in the datamodel: https://docs.python.org/3/reference/datamodel.html
- https://docs.python.org/3/reference/datamodel.html#implementing-descriptors
Applied when instance of class containing the method == descriptor, appears in an owner class
- __get__ get value of attribute for instance or class
- __set__ set value of instance (data descriptor)
- __delete__ delete attribute on instance
- "Descriptor" is an object attribute with binding behavior
- a.x
  - = =x.__get__(a)
  - = =type(a).__dict__['x'].__get__(a, type(a))
  - etc.
- No get means it returns the object itself
@staticmethod & @classmethod are non-data descriptors
Non-data descriptors can be overridden
