I have this class, and I've been pickling it's objects as a file format for my program, which works great. The problems are a.) how to handle things when the user tries to load a non-pickled file, and b.) when they load a pickled file of the wrong class.
a. I can handle with a general exception I guess. I just tried to pickle.load() a .pyc and it failed with a 'KeyError' exception - however that works. It might do that every time, it might not. Regarding b., if I type check I simply get the 'instance' type, which doesn't get me all of the way there because I might have an instance of the wrong class. I can't find any sort of __type__ attribute to set in the objects. Perhaps I should use __str__? -- http://mail.python.org/mailman/listinfo/python-list
