That is usually a good default: <code>order.total</code> is simpler than a pair of trivial getter and setter methods when reading and writing the value needs no extra behavior.</p> <p>Requirements can change. A value may need validation, an attribute may become computed, or an existing public field may need to keep its interface while its internal representation changes. Python&rsquo;s built-in <code>property</code> type lets a class place method logic behind normal attribute access.</p>
