Fixed up the introspection code and tests added for #9779 to run under Python...

        # Walk through and look for references to other tables. SQLite doesn't

        # really have enforced references, but since it echoes out the SQL used

            if not result:

                continue

            other_table_results = result[0].strip()

            other_table_results = other_table_results[li+1:ri]

            for other_index, other_desc in enumerate(other_table_results.split(',')):

                other_desc = other_desc.strip()
