How to expose std::pair to python using boost::python?

Question

How to expose std::pair to python using boost::python? When I expose for example vector<string> I simply write:

class_<std::vector<std::string> >("StringVec")
    .def(vector_indexing_suite<std::vector<std::string> >())
;

But I don't know how to deal with std::pair.

Answer 1

I found a solution. The most simple example of exposing std::pair is:

class_<std::pair<int, int> >("IntPair")
    .def_readwrite("first", &std::pair<int, int>::first)
    .def_readwrite("second", &std::pair<int, int>::second);
