[issue1388872] Polymorphic getters / setters

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

This is normal behavior: the property is created with the functions
created just above, even before they belong to any class.

To make the property search the class hierarchy, you could write: 
  foo = property(lambda x: x.get_foo(), lambda x, v: x.set_foo(v))

or make it a function:
  def polymorphic_property(getter, setter):
      return property(lambda x  : getattr(x, getter)(),
                      lambda x,v: getattr(x, setter)(v))
  [...]
  foo = polymorphic_property('get_foo', 'set_foo')
