 You can also supply the special name ``:memory:`` to create a database in RAM.
 
 Once you have a :class:`Connection`, you can create a :class:`Cursor`  object
 and call its :meth:`~Cursor.execute` method to perform SQL commands::

 Let's assume we initialize a table as in the example given above::
 
-   conn = sqlite3.connect(":memory:")
-   c = conn.cursor()
