Question

For example:

class Example:
    def __init__(self):
        self.v = 0

    @property
    def value(self):
        return self.v
    @value.setter
    def value(self, v):
        self.v = v

class SubExample(Example):
    pass

Would it be possible to rewrite just the getter to value in SubExample?

Answer 1

You can do so like this

class DoubleExample(Example):
    @Example.value.getter
    def value(self):
        return self.v * 2

o = Example()
o.value = 1
print o.value # prints "1"

p = DoubleExample()
p.value = 1
print p.value # prints "2"

However, this only works if Example is a new-style class (class Example(object):) rather than an old style class (class Example:), as it is in your example code.
