初始化函数中的虚函数调用（ C++ vs python ）

代码+结果，不做解释

当然，对于python没有virtual function一说，估计当作对比一个例子看看吧。

 

 

#include <iostream> using namespace std; class base { public: virtual void foo() { cout << "base" << endl; } base() { foo() ;} }; class derive: public base { public: derive() { foo(); } virtual void foo() { cout << "derive" << endl; } }; int main() { derive d; return 0; }

结果：

base
derive

 

class base(object): def __init__( self ): self.foo() def foo( self ): print "base" class derive( base ): def __init__( self ): super( derive , self ).__init__() self.foo() def foo( self ): print "derive" d = derive()

结果：

derive
derive
