vc中调用python代码

运行一句python命令
对vc设置路径
include:D:\PYTHON31\INCLUDE
lib:D:\PYTHON31\LIBS
#include "stdafx.h"
#include "python.h"
int main(int argc, char* argv[])
{
 Py_Initialize() ;
 PyRun_SimpleString("print('Hello')");
 //PyRun_SimpleString("print(dir())");
 Py_Finalize();    
 return 0;
}
编译、连接
拷贝D:\Python31\python31.dll到exe文件目录
运行，输出到控制台
可以运行多行命令
Py_Initialize() ;
PyRun_SimpleString("x=100");
PyRun_SimpleString("print(x)");
PyRun_SimpleString("a=x*x\nprint(a)\n");
Py_Finalize();   
相当于在python下运行下列代码
x=100
print(X)
a=x*x
print(a)
控制台输入 
以下代码解释控制台输入
#include "stdafx.h"
#include "python.h"
int main(int argc, char* argv[])
{
 Py_Initialize() ;
 PyRun_AnyFile(stdin,NULL);
 Py_Finalize();    
 return 0;
}
读取python变量值
将python运行结果读取到vc中
char *cstr;
PyObject *pstr;
PyObject *main_dict;
  
Py_Initialize() ;
PyObject* main_module = PyImport_AddModule("__main__");
main_dict = PyModule_GetDict(main_module);
PyRun_SimpleString("x='abc'");
pstr = PyRun_String("x", Py_eval_input, main_dict, main_dict);
PyArg_Parse(pstr,"s",&cstr); //转换
printf(cstr);
Py_Finalize();
