curious about model classes

Hi all,
Still working through that tutorial. I am just curious: why are none
of the class variables called self.var, but rather just var? For
example:
import models
class Poll(models.Model):
question=models.CharField(max_length=200)

Should that not be
self.question=...
instead? Otherwise, saying something like:
poll=Poll()
poll.question="question?"
should not work; question is not told to be part of the class by way
of self. This may stray from django and into pure python territory, so
sorry if it gets off-topic. I have never seen a class that does not
tie its variables to itself with self or some other keyword. Come to
think of it, there is no __init__ method. I know that it is not
necessary to have one, but I figured I would have seen one to get
things set up.
