Python“属性"和“属性"之间有什么区别?和“属性"?

属性是一种特殊的属性.基本上，当Python遇到如下代码时:

Properties are a special kind of attribute. Basically, when Python encounters the following code:

spam = SomeObject()
print(spam.eggs)

它在spam中查找eggs，然后检查eggs是否有__get__，__set__ 或 __delete__ 方法 — 如果是，则它是一个属性.如果它是一个属性，它会调用__get__方法，而不是仅仅返回eggs对象(就像任何其他属性一样)因为我们正在进行查找)并返回该方法返回的任何内容.

it looks up eggs in spam, and then examines eggs to see if it has a __get__, __set__, or __delete__ method — if it does, it's a property. If it is a property, instead of just returning the eggs object (as it would for any other attribute) it will call the __get__ method (since we were doing lookup) and return whatever that method returns.
