You can only update a dict with another dictionnary (you could also give it an iterable of tuples (key, value) :

playlist = {item1 : value1}
playlist.update({position : title})
print playlist

>>> {item1 : value1, position : title}

playlist.update([(item2, value2),])
print playlist
>>> {item1 : value1, position : title, item2: value2}
