        print(f"\n__init__ called on Student.")

    def __getattribute__(self, key):
        print(f"\n__getattribute__ invoked on Student with key {key}")

        v = super(Student, self).__getattribute__(key)

            print(f"\n{v} has a __get__ method")
            return v.__get__(None, self)
        return v

    print("\nname property of Student being prepared.")
    name = NameDescriptor()  # note that the property is defined as part of the Student class, not instance

    print("\ngrade property of Student being prepared.")
    grade = GradeDescriptor()
