I don't know the rest of this interface, but when I tried it out just now, I drew the conclusion that writerows wants a list of lists, not one single list, which is logical considering the word "rows", not "row".

It may be useful to state that the language is python, also.

That's why we should support this also Programming Talk Suggestion

http://docs.python.org/library/csv.html#writer-objects

The argument to writerows() must be a list, but it can be a list of a lot of things.
