[Tutor] reg: How to import dll in python

[Shweta Kaushik]

Hi,

Please find code used to create dll:

add_1.cpp

#include "add_1.h"
using namespace std;

Mathematics::Mathematics()
{

}

void Mathematics::input()
{
    cout << "Input two inetegers\n";
    cin >> x >> y;
}
void Mathematics::add()
{
cout << "Result = " << x + y;
}

add_1.h
#include <iostream>

class Mathematics {
  int x, y;
public:
            __declspec(dllexport) Mathematics();//constructor
            __declspec(dllexport) void input();
            __declspec(dllexport) void add();
};

Dll created: Addition.dll

Python Code to import above dll:
import ctypes
From ctypes import *
testDll = cdll.LoadLibrary("D:\Python Test Codes\DLL_Test\Addition.dll")
test1 = ctypes.WINFUNCTYPE(None)
test2 = test1 (("add", testDll))

Error Displayed
