#include <string>

class MyClass {

private:

····std::string name;

public:

····std::string getName();

};

А это myclass.i:

%include "string.i"

%module myclass

%{

#include <string>

#include "MyClass.h"

%}

%extend MyClass {

····std::string __repr__()

····{

········return $self->getName();

····}

}
