Explore the __get__ method of Python's descriptor protocol to understand how it manages requests from instances and classes. Learn why descriptors receive both instance and owner parameters and see examples demonstrating their behavior. This lesson helps you grasp how to implement controlled attribute access using descriptors, enhancing your object-oriented programming skills in Python.
