Communicate between python and C ++

I want to create a python module that can call its functions from a C ++ class and call C ++ functions from this class

I was looking at a raise, however it doesn't seem to make any sense this applies to the shared library (which I don’t know how to create it), and I can’t use the code they use in the examples (this seems very confusing)

here is their hi-world study guide ( http://www.boost.org/doc/libs/1_55_0b1/libs/python/doc/tutorial/doc/html/index.html#python.quickstart )

Following the C / C ++ tradition, let's start with hello world. C ++ function:

char const* greet()
{
   return "hello, world";
}

can be displayed in Python by writing the Boost.Python shell:

include <boost/python.hpp>

BOOST_PYTHON_MODULE(hello_ext)
{
    using namespace boost::python;
    def("greet", greet);
}

. . . DLL Python. Python:

>>> import hello_ext
>>> print hello_ext.greet()
hello, world

... Hello World ...
