Error in my code


#1


This code is return a value error : it says that it needs more than one argument to unpack


import random

    "class %%%(object):\n\tdef ***(self, @@@)":
      "class %%% has-a function named *** that takes self and @@@ parameters.",
    "*** = %%%()":

Are you trying to run this in Python 3? If so, there are some changes to make in the code.
