You evidently mean that the scalar you are getting is e.g. "11" and
your loop is returning "1" then "1" again. So there are two
possibilities: a string (either str or unicode) or a list (or some
other sequence).
I'd try this:
if isinstance(returned_value, basestring):
returned_value = [returned_value]
for item in returned_value:
do_something_with(item)
