// error } }● Easy enough to return standard types (int, float, ...) ○ Let bindings library do the heavy lifting ● Can return python objects ○ boost::python::dict / boost::python::list Chose to write all code in Cython instead of C / C++ ● Benefits: ○ Easy interop, Cython writes the bindings for your helper functions ○ Easy syntax, code looks very similar to python ○ Can import C / C++
