import random
class Liar(list):
def __len__(self, things):
self.things = things
return len(self.things) + random.randrange(-3,4, 6)
super().__len__(self, things)
import random
class Liar(list):
def __len__(self, things):
self.things = things
return len(self.things) + random.randrange(-3,4, 6)
super().__len__(self, things)

-
__len__should not take any arguments other than self -
__len__should not be called with any arguments -
super().__len__()should be the basis for creating a "guaranteed wrong" value - anything after a "return" statement is never executed

Python Development Techdegree Student 6,055 PointsOK everybody here's the answer:
import random
import math
class Liar(list):
def __init__(self, *arg):
self.arg = []
def __len__(self):
super().__len__()
randomNum = random.randint(2, 9)
x = len(self.arg) + math.factorial(randomNum)
return x
