Question

Does someone have a nice tip how to port tis PHP function to python?

/**
 * converts id (media id) to the corresponding folder in the data-storage
 * eg: default mp3 file with id 120105 is stored in
 * /(storage root)/12/105/default.mp3
 * if absolute paths are needed give path for $base
 */

public static function id_to_location($id, $base = FALSE)
{
    $idl = sprintf("%012s",$id);
    return $base . (int)substr ($idl,0,4) . '/'. (int)substr($idl,4,4) . '/' . (int)substr ($idl,8,4);
}

Answer 1

In one line, (Python 2.x):

id_to_location = lambda i: '/%d/%d/%d/' % (int(i)/1e8, int(i)%1e8/1e4, int(i)%1e4)

then:

print id_to_location('001200230004')
'/12/23/4/'
