Use

boost::python::handle<>

e.g.

   boost::python::handle<> h(boost::python::allow_null(PyIter_Next(x)));
   if (!h.get()) break; // end of iteration
   boost::python::object o(h);

If you omit allow_null, e.g.

   boost::python::handle<> h(PyIter_Next(x));

an exception is thrown if PyIter_Next(x) returns NULL.

There is also

boost::python::object o(boost::python::borrowed(x));

to indicate that x is a borrowed reference (i.e. o does not take ownership).
