How do I propagate C++ exceptions to Python in a SWIG wrapper library?

Question

I\'m writing a SWIG wrapper around a custom C++ library which defines its own C++ exception types. The library\'s exception types are richer and more specific than standard

Answer 1

From the swig documentation

%except(python) {
try {
$function
}
catch (RangeError) {
    PyErr_SetString(PyExc_IndexError,"index out-of-bounds");
    return NULL;
}
}
