You've got the right idea, but a few issues with the implementation:

  • you don't need to define "List"
  • "Liar" will be based on "list" (lower-case)
  • you don't need to override "__init__"
  • the override of "__len__" doesn't need an argument
  • use "super()" to access the "__len__" of the parent class, and it won't need an argument
