__len__ problem, help me
Now I want you to make a subclass of list. Name it Liar.
Override the len method so that it always returns the wrong number of items in the list. For example, if a list has 5 members, the Liar class might say it has 8 or 2.
You'll probably need super() for this.
import random class Liar(list): def __len__(self, other): super().__len__(self,other) return self# + bool(random.randint(-2, 2))
Bot answer: Bummer: TypeError: len() missing 1 required positional argument: 'other'

You are on the right track.
__len__method doesn’t take arguments so only
selfis needed on the
defline, and no arguments are needed in the super call.
- the results of the super call are not saved
- modify the results from super call and return it.
Post back if you need more help. Good luck!!!
