Couldn't call list methods on `Liar`

Hi. Just a small bump I've hit here. Anyone know?

(I'm feeling my 2 init lines are unneeded, so I'm leaving them in but I've commented out.)


class Liar(list):
#    def __init__(self, *args, **kwargs):
#        self = list.__init__(self, *args, **kwargs)

    def __len__(self):
        n = super().len(self) + 1
        return n

Hi Mark,

You want to call your super's dunder methods the same way that you would inside the super class, not outside of it. e.g. super().__len__() instead of len(args)
