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

Another way to do it, without having to create any additional classes. I've added a set method to show what you do if you only override one of the two:

class Foo(object):
    def _get_age(self):
        return 11

    def _set_age(self, age):
        self._age = age

    age = property(_get_age, _set_age)


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

    age = property(_get_age, Foo._set_age)

This is a pretty contrived example, but you should get the idea.
