Solve the following python programming problem given the following code:
def _import_lazylist_attach_landmarks(built_objects, landmark_resolver, landmark_ext_map = None) : 
    if (landmark_ext_map is not None) : 
        for k in range (len (c)) : 
            x = built_objects [k] 
            lm_paths = partial (landmark_resolver, x.path) 
            def wrap_landmarks(f, index) : 
                obj = f () 
                for (group_name, lm_path) in lm_paths (index).items () : 
                    lms = _import (lm_path, landmark_ext_map, asset = obj) 
                    if (obj.n_dims == lms.n_dims) : 
                        obj.landmarks [group_name] = lms 
return obj 
new_ll = LazyList ([partial (wrap_landmarks, c, i) for (i, c) in enumerate (x._callables)]) 
            built_objects [k] = new_ll
