Sorry I'm confusing at best. What I meant was, because as
self=pickle.load(...) doesn't work (as you found out), you'd need to
manually take the attributes from the unpickled instance.
The easiest way that I can think of...
> class Portfolio:
> def __init__(self, file=None):
> if file is not None:
> if fileExists(file):
> f = open(file, 'r')
unpickled_instance = pickle.load(f)
attributes from unpickled_instance to self
Perhaps there's a better way though. Sorry for giving incomprehensible
