I'm very new to boost python and trying to figure out how to properly

not sure if I need to extract the list from the object or if it's
already a list.
boost::python::object list = exec("Foo.extensions()",
_pyMainNamespace); // where Foo.extensions() is a static method
returning a list of strings
Something like this:
namespace bp = boost::python;
bp::object pyList = bp::exec("Foo.extensions()", _pyMainNamespace);
std::vector<std::string> vec(bp::len(pyList));
for (std::size_t i = 0; i < vec.size(); ++i) {
vec[i] = bp::extract<std::string>(pyList[i]);
}
My end goal is to have a QList of QStrings, but if I can somehow get
them to a boost list of std::strings I can take it from there.
I'll leave converting to Qt stuff up to you. Note that you can also do
extract<char const *>(), which may be more efficient if you have really
large strings and don't want to copy them.
Good Luck!
