vc中調用python代碼

運行一句python命令

對vc設置路徑
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;
}

 

編譯、連接
拷貝D:/Python31/python31.dll到exe文件目錄
運行，輸出到控制檯

可以運行多行命令
Py_Initialize() ;
PyRun_SimpleString("x=100");
PyRun_SimpleString("print(x)");
PyRun_SimpleString("a=x*x/nprint(a)/n");
Py_Finalize();   

 

相當於在python下運行下列代碼

x=100

print(X)

a=x*x

print(a)

 

控制檯輸入 

以下代碼解釋控制檯輸入

 

#include "stdafx.h"
#include "python.h"

int main(int argc, char* argv[])
{
 Py_Initialize() ;
 PyRun_AnyFile(stdin,NULL);
 Py_Finalize();    
 return 0;
}

 

讀取python變量值

將python運行結果讀取到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); //轉換
printf(cstr);
Py_Finalize();
