I have created a base class:

class Thing():def __init__(self, name):self.name = name

I want to extend the class and add to the init method so the that SubThing has both a name and a time property. How do I do it?

class SubThing(Thing):# something here to extend the init and add a "time" propertydef __repr__(self):return '<%s %s>' % (self.name, self.time)

Any help would be awesome.

You can just define __init__ in the subclass and call super to call the parents' __init__ methods appropriately:

class SubThing(Thing):def __init__(self, *args, **kwargs):super(SubThing, self).__init__(*args, **kwargs)self.time = datetime.now()

If you're still on Python 2.x, make sure the base class is a subclass of object, as super won't work with old-style classes:

class Thing(object):...
