The print statement (at least in 2.7) accepts arguments separated by
commas, but ordinary assignment gives a different result:
>>> a = "str", "ing"
>>> a
('str', 'ing')
So, you probably want something like:
attrs = "Hunger: %s Boredom: %s Mood: %s" % (self.hunger,
self.boredom, self.boredom + self.hunger)
