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

Same as @mr-b's but with decorator.

class Foo(object):
    def _get_meow(self):
        return self._meow + ' from a Foo'
    def _set_meow(self, value):
        self._meow = value
    @property
    def meow(self):
        return self._get_meow()
    @meow.setter
    def meow(self, value):
        self._set_meow(value)

This way, an override can be easily performed:

class Bar(Foo):
    def _get_meow(self):
        return super(Bar, self)._get_meow() + ', altered by a Bar'
