You are doing this step too soon.  These next two lines should be
deferred until you have finished collecting all of your data.  Notice
that you are using artists to store a list of artist names.  And then
you use artists to store the (artist,painting,value) tuples that you
create using zip.

(Put them here)
artists=zip(artists,paintings,values)
artists.sort()
