qt如何调用python

#include <QCoreApplication>//包含调用Python相应的头文件#include <Python.h>int main(int argc, char *argv[]){
 QCoreApplication a(argc, argv);
 //初始化Python解释器，这是调用操作的第一步
 Py_Initialize();
 if( !Py_IsInitialized() ){
 return -1;
 }
  //执行单句Python语句，用于给出调用模块的路径，否则将无法找到相应的调用模块
 PyRun_SimpleString("import sys");
 PyRun_SimpleString("sys.path.append('./')");//获取qt_python_fun.py模块的指针
 PyObject* pModule = PyImport_ImportModule("qt_python_fun");
 if (! pModule){
 printf("Can't open python file\n");
 return -1;
 }//获取hello函数的指针
 PyObject* pFunhello = PyObject_GetAttrString(pModule,"hello");
 if (!pFunhello){
 printf("Get function hello failed\n");
 return -1;
 }//调用函数，传入参数为NULL
 PyObject_CallFunction(pFunhello,NULL);//销毁Python解释器，这是调用的最后一步
 Py_Finalize();
 return a.exec();}
