Do not judge strictly)
Hello C++ people)
I am learning Python 3 and set myself the task of translating the glut library into Python 3
Here is the header file

PythonGlut.hpp

#include <glut.h>                       //подключаем заголовочный файл glut.h
#pragma comment (lib, "glut32.lib")    // link with Win32 GLUT lib

namespace pyglut{
    class PythonGlut{
        public:
            PythonGlut();
            ~PythonGlut();

            // Инициализация GLUT и создание окна
            void PythonGlutInitDisplayMode(unsigned int mode);
    };

}

Here is another C++ file (I don't know what to name it)

PythonGlut.cpp

#include "PythonGlut.hpp" //подключаем заголовочный файл PythonGlut.hpp

namespace pyglut{

    PythonGlut::PythonGlut() { }
    PythonGlut::~PythonGlut() { }

    // Инициализация GLUT и создание окна

    void PythonGlut::PythonGlutInitDisplayMode(unsigned int mode){
        glutInitDisplayMode(mode);
    }

}

And here is the implementation

glut_window.cpp

#include "PythonGlut.hpp"

using namespace pyglut;

int main(int argc, char **argv) {

    //создаем объект типа PythonGlut
    PythonGlut pythonglut;

  // инициализация
    pythonglut.PythonGlutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

  return 1;
}

I have 2 questions >
1 Have I created the files correctly? If not, please tell me how.
Do not send to Google there was, in the examples everything is different.
2 How to fix this error
