data descriptor

基本解释

In any case, a data descriptor is more general, so I'll show you one.
无论如何，数据描述符更为常见，因此我将向您展示一个例子。
The non-data descriptor is likely to be used to return a callable object.
非数据描述符最常用于返回一个可调用对象。
A non-data descriptor is, in a sense, often a fancy name for a method -- but the particular method returned by descriptor access could be determined at runtime.
某种意义上讲，非数据描述符通常是某种方法的一个好听的名字 —— 但是可以在运行时确定描述符访问所返回的特定方法。
