How to call a property of the base class if this property is being overwritten in the derived class?

Question

I\'m changing some classes of mine from an extensive use of getters and setters to a more pythonic use of properties.

But now I\'m stuck because some of my previous

You can use the following template:

class Parent():
    def __init__(self, value):
        self.__prop1 = value

    #getter
    @property
    def prop1(self):
        return self.__prop1

    #setter
    @prop1.setter
    def prop1(self, value):
        self.__prop1 = value

    #deleter
    @prop1.deleter
    def prop1(self):
        del self.__prop1
  
class Child(Parent):

    #getter
    @property
    def prop1(self):
        return super(Child, Child).prop1.__get__(self)

    #setter
    @prop1.setter
    def prop1(self, value):
        super(Child, Child).prop1.__set__(self, value)

    #deleter
    @prop1.deleter
    def prop1(self):
        super(Child, Child).prop1.__delete__(self)

Note! All of the property methods must be redefined together. If do not want to redefine all methods, use the following template instead:

class Parent():
    def __init__(self, value):
        self.__prop1 = value

    #getter
    @property
    def prop1(self):
        return self.__prop1

    #setter
    @prop1.setter
    def prop1(self, value):
        self.__prop1 = value

    #deleter
    @prop1.deleter
    def prop1(self):
        del self.__prop1


class Child(Parent):

    #getter
    @Parent.prop1.getter
    def prop1(self):
        return super(Child, Child).prop1.__get__(self)

    #setter
    @Parent.prop1.setter
    def prop1(self, value):
        super(Child, Child).prop1.__set__(self, value)

    #deleter
    @Parent.prop1.deleter
    def prop1(self):
        super(Child, Child).prop1.__delete__(self)
