我用python弄了半天没搞定,高手来看下,我使用的是cursor.executemany来实现插入

示例数据:

<code class="lang-python">{
    'info': {
        'files': [
            {'path': ['Runner Runner [2013]HDRip XviD-SaM[ETRG].avi'], 'length': 733460868}, 
            {'path': ['SaMple.avi'], 'length': 5577446}, 
            {'path': ['ETRG.mp4'], 'length': 1515390}, 
            {'path': ['RUNNERR-ETRG.nfo'], 'length': 7806}, 
            {'path': ['Torrent Downloaded From ExtraTorrent.cc.txt'], 'length': 367}
        ]
    }
}
</code>

我写的处理:

<code class="lang-python">values = []
for i in data['info']['files']:
    values.append(i['path'][0])   
    cur.executemany('INSERT INTO `btss`.`magnetic_file` (`Uuid`, `Hash`, `File`, `Size`) VALUES (NULL, \'%s\', \'%s\', \'%s\')', values)
</code>

我这样用是不对的,但是append只能一个参数,请教该如何处理
新手哈,刚开始学

多append几次 - -。也可以不用append。
另外values放在for里面声明
