/data/python/caiji_asc.py

/data/python/caiji_desc.py

两个文件的代码几乎一样的，就是查询mysql的时候order 排序不一样

下面是具体代码，刚学几天，网上东拼西凑出来的，高手帮忙看看吧

我用ssh连接服务器 运行这两个python 程序始终都是一个运行了另一个自动exit。。实在不明白怎么回事？？

os.chmod(row['path'], 0777);

mysql.execute("delete from image where id = %s", row['id']);

passTime = int(time.time()) - int(startTime);

if passTime >= 3600:

break;

print str(row['id']);

mysql.close();

conn.close();
