換句話說，就是需要把C++封裝成Python可以“理解”的類型。通過使用C++實現測試激勵的內部邏輯，然后Python調用C++的這個實現函數即可，這樣可以大大減輕腳本編寫的速度以及復雜度。

#include <boost/python.hpp>

include <boost/python/module.hpp>
include <boost/python/def.hpp>
include <boost/python/to_python_converter.hpp>

using namespace std; 
using namespace boost::python;
namespace HelloPython{ 
// 簡單函數 
char const* sayHello(){ 
    return "Hello from boost::python"; 
}
// 簡單類 
class HelloClass{ 
public: 
    HelloClass(const string& name):name(name){ 
    } 
public: 
    string sayHello(){ 
      return "Hello from HelloClass by : " + name; 
    } 
private: 
    string name; 
}; 
// 接受該類的簡單函數 
string sayHelloClass(HelloClass& hello){ 
    return hello.sayHello() + " in function sayHelloClass"; 
}
//STL容器 
typedef vector<int> ivector;
//有默認參數值的函數 
void showPerson(string name,int age=30,string nationality="China"){ 
    cout << name << " " << age << " " << nationality << endl; 
}
// 封裝帶有默認參數值的函數 
BOOST_PYTHON_FUNCTION_OVERLOADS(showPerson_overloads,showPerson,1,3) //1:最少參數個數,3最大參數個數
// 封裝模塊 
BOOST_PYTHON_MODULE(HelloPython){ 
    // 封裝簡單函數 
    def("sayHello",sayHello);

// 封裝簡單類，并定義__init__函數 
class_("HelloClass",init()) 
  .def("sayHello",&HelloClass::sayHello)//Add a regular member function 
  ; 
def("sayHelloClass",sayHelloClass); // sayHelloClass can be made a member of module!!!

// STL的簡單封裝方法 
class_("ivector") 
  .def(vector_indexing_suite()); 
class_ >("ivector_vector") 
  .def(vector_indexing_suite >());

// 帶有默認參數值的封裝方法 
def("showPerson",showPerson,showPerson_overloads());
