class A(object): def __init__(self,name): = name def getName(self): return 'A'+ a = A('hello') print a.getName() 当我们执行 a = A('hello') 可以理解为: a=object.__new__(A) A.__init__(a,'hello') 也就是说,当我们初始化一个对象的时候,首先执行的不是__init__()方法...
方法前面的 +/- 号代表函数的类型:加号(+)代表类方法(class method),不需要实例就可以调用,与C++ 的静态函数(static member function)相似。减号(-)即是一般的实例方法(instance method)。 这里提供了一份意义相近的C++语法对照,如下: classMyObject:publicNSObject{protected:intmemberVar1;// 实体变量void*membe...

classPoint{public:voidinit(){}staticvoidoutput(){}};voidmain(){Point::init();Point::output();} 报错: 'Point::init':illegal call of non-staticmemberfunction 结论1:不能通过类名来调用类的非静态成员函数。 通过类的对象调用静态成员函数和非静态成员函数。
