array of strings in boost python
Hi, newbie in python and boost::python I have a method in c++ that returns a vector of strings, how can i expose this method in python, and how should i use it in python class A { public: std::vector<std::string> getName(); }; BOOST_PYTHON_MODULE(pysession) { class_<A>("A") .def("GetName" ,&A::getName) } now in python how could i call the function getName() ? here is my error in python TypeError: No to_python (by-value) converter found for C++ type: class std::vect or<class std::basic_string<char,struct std::char_traits<char>,class std::allocat or<char> >,class std::allocator<class std::basic_string<char,struct std::char_tr aits<char>,class std::allocator<char> > > > not valid thanks, Charles.

Sorry to turn the question around on you, but how do you /want/ to be able to use it in Python? That will determine how you should expose it. You might look into http://boost.org/libs/python/doc/v2/indexing.html#vector_indexing_suite_clas... to see if it meets your needs. -- Dave Abrahams Boost Consulting www.boost-consulting.com

Wouldn't putting this in http://www.boost.org/libs/python/doc/index.html reduce the B.Py traffic on this list? The URL you refer to (http://www.python.org/community/sigs/c++-sig/) gives a 404, a working c++-sig page can be found at http://www.python.org/community/sigs/current/c++-sig/ Sadly, there's no mention of a mailing list on that page, and the only three links point back to boost.org. You need to read the Mailing Lists page (main menu on the left) carefully to catch the "complete listing of python.org's mailing lists" at the very top. Minor bitching aside, thanks for B.Py! -- How many Vietnam vets does it take to screw in a light bulb? You don't know, man. You don't KNOW. Cause you weren't THERE. http://bash.org/?255991

I don't know, but it's not a bad idea.

Ouch.
a working c++-sig page can be found at http://www.python.org/community/sigs/current/c++-sig/

Could you submit patches to repair these problems? It would be much appreciated! -- Dave Abrahams Boost Consulting www.boost-consulting.com
