python from c++ in visual studio

Question

I used the visual studio installer to install python and could run the basic python program. Now I want to make a new c++ console program and call the python script from there.

When googling I saw I need to include the "Python.h" in my c++ function. I tried to include and i get the message "cannot open the source file". Is it because I used visual studio to install the python. And most of googling have installed python separately.

Answer 1

Older versions of visual studio, just installed python interpretter. So installed Visual studio 2019 and had a option to select Python3

With that option, it created a new directory, C:\Python27amd64\

Now I created a new console application: Code:

#include <iostream>
#include "C:\Python27amd64\include\Python.h"

    int main()
    {
        Py_Initialize();
        PyRun_SimpleString("from time import time,ctime\n"
         "print('Today is',ctime(time()))\n");
        //std::cout << "Hello World!\n";
    }

And also followed the following steps:

1. Properties > C/C++ > General > Additional Include Directories. I added the "C:\Python27amd64\include" 2.Properties > Linker > General > Additional Library Directories. : I added C:\Python27amd64\libs 3.Properties > Linker > Input > Additional Dependencies: I added python27.lib
2. I changed the build to "Release x64". Because it couldnot find the debug libraries
