[Tutor] Where's the Walrus?

[Rick Pasotto]

1) next_personality is a method so python needs the parens when it is called.

2) your definition of next_personality should have a 'self' arg.

3) self.which will become a 4 which is out of range. The way I code this
   type of situation is:

	self.which = (self.which + 1) % 4

   (instead of using an if statement)
   which makes sure self.which is only 0, 1, 2, or 3.
