You want to use flat=True in your values_list query.

From the docs:

This is similar to values() except that instead of returning dictionaries, it returns tuples when iterated over.

If you only pass in a single field, you can also pass in the flat parameter. If True, this will mean the returned results are single values, rather than one-tuples.
