I think what you want to do is this:
class foo (object):
def __init__(self, len=9):
self._len = len
def foo2(self, len=None):
if len is None:
len = self._len
# ...
Default arguments are for when you want to use exactly the same object
each time the function/method is called. If you the object you want to
use depends on something, you can use this arg=None idiom.
