If I do this:
print 'LEN OF BOOK BEFORE APPEND: ', len(pickle.dumps(self.__m_rw)) self.__m_rw.books.append( [p_col1,p_col2,p_col3] ) print 'LEN OF BOOK AFTER APPEND: ', len(pickle.dumps(self.__m_rw)) I get the same length before and after append. when I print self.__m_rw.books, I see my 'appends' in there, yet the pickled object does not change. Any clue ? Thanks Philippe -- *************************** Philippe C. Martin SnakeCard LLC www.snakecard.com *************************** -- http://mail.python.org/mailman/listinfo/python-list
