Export variable into python from C++ using boost.python

Question

I have, for example, a varibale in c++:

const float Pi = 3.1415926535898f;

What is the best way to export it into python-module using boost.python?

I want to access it as variable in global scope.

Answer 1

Seems that it can be easily done using:

boost::python::scope().attr("Pi") = Pi;
