setter Data sources may differ, and may be used for many reasons, so validating data there is not a good idea. Object has to keep correct data, so it should validate it. If you want to have object created no matter what, you can add validate() method, but you may also use setters for this - error will be raised every try to set wrong data. -- http://mail.python.org/mailman/listinfo/python-list
