Class是一个模版,一个蓝图文件,用来描述具有通用属性的对象(Object)的描述文件(数据以及方法)。 Object和Instance本质上是一样的含义,指的都是通过模版(Class)初始化的实例/对象。只是在不同场景可能选择不同用词(Instance更具体化一些)。 书中的定义 Object-Oriented Software Engineering这本书中对于这三个名次的定...

和Python以及Ruby不同的是，C++里class本身不是object，所以class就*不应该*是另一个class的成员。把一...
Functions in Python are first class citizens. This means that they support operations such as being passed as an argument, returned from a function, modified, and assigned to a variable. This property is crucial as it allows functions to be treated like any other object in Python, enabling gr...
In the above example, theStudentclass inherits all the methods and properties of thePersonclass. Hence, theStudentclass will now have thenameproperty and thegreet()method. Then, we accessed thegreet()method ofStudentclass by creating astudent1object. ...
You need to modify the class hierarchy of an instance object that has already been instantiated. Solution A rather unusual application of the mix-in concept lets us perform this task in Python 2.0 or later (with some limitations in Python 2.2): ...
对象x是由class A生成,但是其类型却不是A,而是‘instance’,不仅如此,在新式类出现之前,所有的对象,其类型均是instance,python官方对其的解释是: Up to Python 2.1 the concept of class was unrelated to the concept of type, and old-style classes were the only flavor available. For an old-style class...
