Oh I don't know, people do it all the time -- just not the way the OP 
did :)

Or explicitly pass an instance to the method when calling from the class:

TheClass.method(TheClass(constuctor_arguments_here))


Which strangely enough, is useful at times.

class K(parent):
    def method(self, args):
        x = parent.method(self, args)
        return x + 1
