"self" is conceptually necessary. Notice the similarities between
doittoit() and It.doittoit():
py> def doittoit(it):
... print it.whatzit
...
py> class It:
... whatzit = 42
... def doittoit(self):
... print self.whatzit
...
py> anit = It()
py> doittoit(anit)
42
py> It.doittoit(anit)
42
py> anit.doittoit()
42
If you get this example, I'm pretty sure you will understand "self" and
its necessity.
