Feature request, so to say: limit output to last N playlists

[uahim]

as my Python skills are limited, could anyone explain a way/propose a code change snippet in order to only fetch the last n playlists, instead of all of them?
thanks in advance

currently, this is what I got; it may be ugly - and the script quits with an error - but it does work
