Here are my averagely general class methods for creating a dictionary from the result of database queries:

def make_schema_dict(self):
    schema = [i[2] for i in self.cursor.tables()
              if i[2].startswith('tbl_') or i[2].startswith('vw_')]

    self.schema = {table: {'scheme': [row.column_name for row
                                      in self.cursor.columns(table)]}
                   for table in schema}

def last_table_query_as_dict(self, table):
    return {'data': [{col: row.__getattribute__(col) for col in self.schema[table]['scheme']
                      if col != 'RowNum'} for row in self.cursor.fetchall()]}
Unfortunately as you can see, there are many complications.

For example, when multiple tables are queried; some hackish lambdas are required to generate the resulting dictionary.

Can you think of some more general methods?

(and yes I know this is against the PEP; and that this is also on SO)
