Boost.PythonHeader <boost/python/raw_function.hpp> |
raw_function(...)
is used to convert a function taking a tuple and a dict into a Python callable object
which accepts a variable number of arguments and arbitrary keyword
arguments.
template <class F> object raw_function(F f, std::size_t min_args = 0);
f(tuple(), dict()) is
well-formed.min_args arguments. When called, the actual non-keyword arguments will be passed in a tuple as the first argument to f, and the keyword arguments will be passed in a dict as the second argument to f.

using namespace boost::python;
tuple raw(tuple args, dict kw)
{
return make_tuple(args, kw);
}

{
def("raw", raw_function(raw));
}
Python:
>>> from raw_test import *
>>> raw(3, 4, foo = 'bar', baz = 42)
((3, 4), {'foo': 'bar', 'baz': 42})
