Hi Adrian, One easy way, is to append the objects to a list, as you have mentioned and call the state method in iteration. l = [] l.append(man) l.append(woman) # Print the state. for item in l: print item.state() (If I understood right, man and woman qualifies as "every instance of man") -N -- http://mail.python.org/mailman/listinfo/python-list
