#include <boost/python/tuple.hpp>
using namespace boost::python;

class A {
public:
    A() {
        M=make_tule("ab","cd","1234");
    }

    bool find(std::string ss) {
        //How to find an object from tuple "M" and return "true" or
"false",. The function "find" would work in c++.
    }
    tuple M;
}

BOOST_PYTHON_MODULE(ctopy)
{
    class_<A> ("A",init<>())
        .add_property("M",&A::M)
    ;
}
