This is because that list is an attribute of the class. Instances have a reference of this class attribute, but it can be replaced by an attribute of the instance with self (self is a reference to the instance and not the class. This example might help: py> class C(object): ... value = 42 ... def separate_from_pack(self, some_value): ... self.value = some_value ... py> C.value 42 py> c1 = C() py> c1.value 42 py> c2 = C() py> c2.value 42 py> c2.separate_from_pack(88) py> c2.value 88 py> C.value 42 py> c3 = C() py> c3.value 42 James -- James Stroud UCLA-DOE Institute for Genomics and Proteomics Box 951570 Los Angeles, CA 90095 http://www.jamesstroud.com/ -- http://mail.python.org/mailman/listinfo/python-list
