    <p>I'm working on making a small app/script for putting my mp3's in a folder hierarchy the way I want it, as I haven't found a solution for Unix that is just quite right. So I decided to work on my own. This is an excerpt</p> <pre><code>if musfile[0]: m = musfile[0] tag.link(m) mar = str(tag.getArtist()) mal = str(tag.getAlbum()) mti = str(tag.getTitle()) #m1track = str(tag.getTrack()) os.rename(m,mar + ' - ' + mti + '.mp3') m = mar + ' - ' + mti + '.mp3' os.makedirs(newmusicdir + '/' + mar + '/' + mal + '/') shutil.copy(m,newmusicdir + '/' + mar + '/' + mal + '/') if musfile[1]: m = musfile[1] tag.link(m) mar = str(tag.getArtist()) mal = str(tag.getAlbum()) mti = str(tag.getTitle()) #m1track = str(tag.getTrack()) os.rename(m,mar + ' - ' + mti + '.mp3') m = mar + ' - ' + mti + '.mp3' os.makedirs(newmusicdir + '/' + mar + '/' + mal + '/') shutil.copy(m,newmusicdir + '/' + mar + '/' + mal + '/') </code></pre> <p>And so on. However, in order to organize more than one file, I have been just reusing blocks of code. However, this is extremely inefficient for several blocks of code. For example, if I wanted to organize just 50 songs with my method, I would have over 500 lines of code, for something so simple. So I was wondering if there is anyway I could use loops. However, the problem with using loops is that with each block I must change the number in the list. For example, from block one to two, I must change <code>musfile[0]</code> to <code>musfile[1]</code>, and I do not know how to do that with loops. In fact I have little knowledge about loops. Am I clear enough? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
