(nodes)
Return a native Python type from the list of compiled nodes. If the
    result is a single node, its value is returned. Otherwise, the nodes are
    concatenated as strings. If the result can be parsed with
    :func:`ast.literal_eval`, the parsed value is returned. Otherwise, the
    string is returned.
