If you have parameters in the query, % is used as placeholder prefix.
You must use %% to include a literal % in the query:
In [14]: cur.execute("""select email_address from customer where
email_address like '%%' || %s || '%%'""", ('matt',))
or you can add the % to the value instead of the query:
In [17]: cur.execute("""select email_address from customer where
email_address like %s""", ('%matt%',))
Hope this helps,
