python properties and inheritance

Question

I have a base class with a property which (the get method) I want to overwrite in the subclass. My first thought was something like:

class Foo(object):
    d         


        

Answer 1

Something like this will work

class HackedProperty(object):
    def __init__(self, f):
        self.f = f
    def __get__(self, inst, owner):    
        return getattr(inst, self.f.__name__)()

class Foo(object):
    def _get_age(self):
        return 11
    age = HackedProperty(_get_age)

class Bar(Foo):
    def _get_age(self):
        return 44

print Bar().age
print Foo().age
