在python中使用mysql插入来对抗空值和撇号

下面的代码是我正在努力处理的mysql插入。如果我能让它接受Nones（我需要插入不同数量的null），那么我就不能让它接受撇号。目前，我似乎遇到了空值的问题

        sql = "INSERT INTO `dtdbtest`.`card` (`pack_id`,`type_id`,`shooter_id`,`gang_id`,`ts`,`code`,`number`,`quantity`,`title`,`keywords`,`text`,`flavor`,`illustrator`,`cost`,`rank`,`upkeep`,`production`,`bullets`,`influence`,`control`,`wealth`) VALUES ({},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{});"

        cur.execute(sql, [packid, typeid, shooterid, gangid, card['last-modified'], card['code'], card['number'], card['quantity'], card['title'], card['keywords'], card['text'], card['flavor'], card['illustrator'], card['cost'], card['rank'], card['upkeep'], card['production'], card['bullets'], card['influence'], card['control'], card['wealth']])
        db.commit()

下面是sql汇编的输出和传递给cur.execute（）的列表

    INSERT INTO `dtdbtest`.`card` (`pack_id`,`type_id`,`shooter_id`,`gang_id`,`ts`,`code`,`number`,`quantity`,`title`,`keywords`,`text`,`flavor`,`illustrator`,`cost`,`rank`,`upkeep`,`production`,`bullets`,`influence`,`control`,`wealth`) VALUES ({},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{});

         67             poop = [packid, typeid, shooterid, gangid, card['last-modified'], card['code'], card['number'], card['quantity'], card['title'], card['keywords'], card['text'], card['flavor'], card['illustrator'], card['cost'], card['rank'], card['upkeep'], card['production'], card['bullets'], card['influence'], card['control'], card['wealth']]
         68             print poop
    ---> 69             cur.execute(sql, [packid, typeid, shooterid, gangid, card['last-modified'], card['code'], card['number'], card['quantity'], card['title'], card['keywords'], card['text'], card['flavor'], card['illustrator'], card['cost'], card['rank'], card['upkeep'], card['production'], card['bullets'], card['influence'], card['control'], card['wealth']])
         70             db.commit()
         71
