This is OK; the C++-sig (http://www.python.org/sigs/c++-sig/) is better. I'm cross-posting there. > I'm interested in getting started with boost python.

Uh-huh. > What options are available to interface between an (efficient) > python-accessible container and c++ stl-style containers? What kind of interface did you have in mind? I mean, there are a lot of options in C++ and Python . You can fairly easily expose STL containers to Python. Then you can use them together with numarray arrays from Python.

Hmm? vector<X> for any X is just a class you can wrap like any other, and then you can construct it from Python like any other. Am I missing something? > Is the reverse a feasible solution? Use python numarray containers and pass > iterators to c++ algorithms for computation? Do you know how to get iterators out of a numarray? Probably you can easily get pointers, which are fine. So, sure, you can do that. You'd want to expose thin wrapper functions which accept boost::python::array arguments and then unpackage the iterators to pass on to the algorithms.
