What error message are you getting? The only thing that I can see which 
*might* be causing you trouble is your use of the 'format' paramstyle 
rather than the prescribed 'qmark' style.

If you change your execute statement to;

     cursor.execute("update items set title=? where title='Title'", (j,))

You may get a different outcome.

For a definition of the different paramstyles, check the DB-API 
specification at http://www.python.org/peps/pep-0249.html
