+1 Everything in Python is an object. Objects can perform an almost-unlimited range of services, fulfilling a wide variety of purposes. A property constrains the object to more focussed functionality ... eg an integer which may not hold a negative value, a string which may not be empty... -- Regards, =dn -- https://mail.python.org/mailman/listinfo/python-list
