                                result.append("Ïî óñëóãå '%s' çàôèêñèðîâàíî %s æàëîá" % (row[0], row[1]))

                        if len(result) > 0:
                                print "<br>".join(result)
                                sys.exit(ex_code)
                        else:
                                sys.exit(0)

我试着把它放在这里 - print "<br> <td class="statusWARNING>".join(result) 但它不起作用。

我认为 statusWARNING 之前的引号是把事情搞砸了。 尝试用斜杠转义它\

cur.execute("SELECT subcategory_name, complains_qty FROM cms_data_view WHERE subcategory_id     = %s AND %s AND dt IN (SELECT max(dt) FROM cms_data_view GROUP BY subcategory_id)" % (int(sys.argv[1]), where_statement))
                if cur.rowcount > 0:
                        result = []
                        for row in cur.fetchall():
                                result.append("По услуге '%s' зафиксировано %s жалоб" % (row[0], row[1]))

                        if len(result) > 0:
                                print "<br> <td class=\"statusWARNING>".join(result)
                                sys.exit(ex_code)
                        else:
                                sys.exit(0)
