在C中运行python对象

int main () {
    // as you know,the python object has its member variables etc,and 
    // I want it to be initialized only once
    py = python_object();   
    while (1) {
        // here,I am hoping to call a member function from the object continously
        // and get a return value. 
        int abc = py.get_num(); 
        if (abc < 0) break;
        do_something_in_my_cpp_code();
    }


}

我在这里讨论的python对象Capture oOjbect.

我想知道这有多难,如果你们有任何处理这类事情的经验.我也对其他可能的方法开放,例如反向(在python脚本中运行C对象).谢谢！
