Solve the following python programming problem given the following code:
def _SetDefaultOrNamedAssignArgListSubtype(self, node) : 
    def HasDefaultOrNamedAssignSubtype(node) : 
        if isinstance (node, pytree.Leaf) : 
            if (format_token.Subtype.DEFAULT_OR_NAMED_ASSIGN in pytree_utils.GetNodeAnnotation (node, pytree_utils.Annotation.SUBTYPE, set ())) : 
                return True 
return False 
has_subtype = False 
        for child in node.children : 
            has_subtype |= HasDefaultOrNamedAssignSubtype (child) 
return has_subtype 
if HasDefaultOrNamedAssignSubtype (child) : 
        for child in node.children : 
            if (pytree_utils.NodeName (child) != 'COMMA') : 
                self._AppendFirstLeafTokenSubtype (child, format_token.Subtype.DEFAULT_OR_NAMED_ASSIGN_ARG_LIST)
