[Tutor] Modifying game of life

[Kent Johnson]

      if randval > perc:
          EMPTY <= you don't need the lines like this, they don't do anything
          return EMPTY

And you can test for less-than-or-equal in one test
      elif randval <= perc:
          return PERSON

in fact since one of the tests has to be true you can just use else:

      if randval > perc:
          return EMPTY
      else:
          return PERSON
