I am working with the last.fm-API.

I have a problem with the currently playing song.
Here is an example of a JSON-output:

As you can see, the first song, which is currently playing has an @attribute

"@attr":{"nowplaying":"true"}

Here is some code:

info = last.read('user.getRecentTracks', user='xxxx')
for track in info['recenttracks']['track']:
        title = track['name']
        url = track['url']
        by = track['artist']['#text']
        form = '#np ' + by + ' - ' + title + ' ' + url

        np = track['@attr']['nowplaying']

Everything works fine except for np!
Is it because of the @?

    Not all tracks have a @attr key, test for it first:

    np = track['@attr']['nowplaying'] if '@attr' in track else ''

    In fact, only the very first entry has that key, probably because you only play one track at a time, the topmost one in the list of tracks played.
