I really like the online documentation features of python. However, I wonder about the output of the following simple example:
class Descriptor(object):
 """Doc of a non-data descriptor."""
 def __get__(self, instance, owner):
 return 42 if instance else self
class GetSetDescriptor(Descriptor):
 """Doc of a data-descriptor."""
 def __set__(self, instance, value):
 pass
class Demo(object):
 non_data = Descriptor()
 data = GetSetDescriptor()
help(Demo)
This results in
Help on class Demo in module __main__:
class Demo(builtins.object)
 | Methods defined here:
 | 
 | non_data = <__main__.Descriptor object>
 | ----------------------------------------------------------------------
 | Data descriptors defined here:
 | 
 | __dict__
 | dictionary for instance variables (if defined)
 | 
 | __weakref__
 | list of weak references to the object (if defined)
 | 
 | data
 | Doc of a data-descriptor.
I think the behaviour of pydoc wrt. the non_data descriptor is a bit out of line. I would have expected to find the docstring in the output here.
