You might've already thought of this (and it is annoying), but you
could pass the name through the descriptor's init method. I believe
this is the only way besides assigning a metaclass that will look for
that type of descriptor upon class creation and set the descriptor's
name at that time.
class A(object):
def __init__(self, attr_name):
self._name = attr_name
def __set__(self, instance, value):
self.instance.__dict__[self._name] = value
# or something like that...
class B(object):
foo = A('foo')
Thanks, this seems to be the less "magical" solution. I don't like having
to repeat the attribute name, but nothing is perfect...
And thanks to Rainer Mansfeld too; looking up the matching attribute may
be useful in other cases.
