Not all such attributes are actually found in instance.__dict__. >>> class Example(object): ... __slots__ = 'spam' ... >>> x = Example() >>> y = Example() >>> x.spam = 23 >>> >>> x.__dict__['spam'] Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'Example' object has no attribute '__dict__' >>> x.spam 23 >>> y.spam Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: spam So it is possible to have per-instance attributes that don't live inside the instance __dict__. >> 2.)

Or dynamic attributes returned by __getattr__ or __getattribute__. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
