How to import multiple python modules with same name with C++

I use PyImport_ImportModule to import python module in C++.

Now i have two Python module files with same name in different folder like: 

c:\Demo1\plugin.py and c:\Demo2\plugin.py

I know in python, can use

import Demo1.plugin as p1
import Demo2.plugin as p2

How to do it in C++, with PyImport_ImportModule or otherwise?

I find a workaround: execute python c:\Demo1\plugin.py and get the output from it, but it isn't a good solution.

To just import a file I would use PyObject* PyImport_ImportModule(const char *name)

PyObject *p1 = PyImport_ImportModule( "Demo1.plugin" );
PyObject *p2 = PyImport_ImportModule( "Demo2.plugin" );

which should work just fine if your path is set correctly. Alternatively you can use PyObject* PyImport_Import(PyObject *name), but then you have to manage the refcounting of the name.

PyObject *s1 = PyUnicode_FromString( "Demo1.plugin" );
PyObject *s2 = PyUnicode_FromString( "Demo2.plugin" );

PyObject *p1 = PyImport_Import( s1 );
PyObject *p2 = PyImport_Import( s2 );

Py_DECREF( s1 );
Py_DECREF( s2 );

You may need to add an __init__.py file to the Demo1 and Demo2 folders.

You can include them in this manner

include "headers/myHeader.h"
include "../moreHeaders/myHeader.h"

Just make sure to use different namespaces in both of the header files to access the variables and functions
