I've attached a quick hack of an implementation, just to play with it
and see how it feels. Here's an example use:
from property import property
class Base(object):
@property
def attribute(self):
print("Base.attribute (getter)")
return 42
@property.get(attribute)
def rwattribute(self):
print("Base.rwattribute (getter)")
return self.attribute * 2
@property.set(rwattribute)
def rwattribute(self, value):
print("Base.rwattribute (setter)")
self.saved = value
class Derived(Base):
@property.get(Base.attribute)
def roattribute(self):
print("Derived.roattribute (getter)")
return self.attribute / 2
