Why do managed attributes just work for class attributes and not for instance attributes in python?

Question

To illustrate the question check the following code:

class MyDescriptor(object):
  def __get__(self, obj, type=None):
    print \"get\", self, obj, type
             


        

Answer 1

You should read this and this.

It overwrites the function because you didn't overload the __set__ and __get__ functions of SomeClass but of MyDescriptor class. Maybe you wanted for SomeClass to inherit MyDescriptor? SomeClass1 prints the "get" and "set" output because it's a static method AFAIK. For details read the upper links.
