Simple statefulness

[aaronschif]

First way

class Game(object):
  def __init__(self):
    "setup"

  def is_done(self):
    pass

  def tick(self, dt):
    pass

while True:
  game = Game()
  while not game.is_done():
    game.tick()
    sleep(1)

More complex, more flexible way.

def game():
  not_done = True
  "setup"
  while not_done:
    "do some stuff"
    yield

while True:
  for _ in game:
    sleep(1)

The second one can be nested, like you can have states in states (easier in python 3).

I would suggest the first way.
