well, if we can create 2 iterable sequences one which contains the user
the other the scores, it should work
the error means that the second argument to the zip function was not an
iterable, such as a list tuple or string
can you show me the lines you're using to retrieve the data sets from
the database? then i might be able to tell you how to build the 2 lists
