In the example below, the Sqlite database is created in the file foobar.db, where a table called tb_fruta is created and its items manipulated (inclusion, alteration and exclusion) through commands SQL:

import sqlite3

conn = sqlite3.connect('foobar.db')

c = conn.cursor()

c.execute("CREATE TABLE tb_fruta ( id integer, nome text );")

c.execute("INSERT INTO tb_fruta ( id, nome ) VALUES ( 1, 'BANANA' );");
c.execute("INSERT INTO tb_fruta ( id, nome ) VALUES ( 2, 'LARANJA' );");
c.execute("INSERT INTO tb_fruta ( id, nome ) VALUES ( 3, 'MELANCIA' );");
c.execute("INSERT INTO tb_fruta ( id, nome ) VALUES ( 4, 'MACA' );");
c.execute("INSERT INTO tb_fruta ( id, nome ) VALUES ( 5, 'UVA' );");
c.execute("INSERT INTO tb_fruta ( id, nome ) VALUES ( 6, 'MORANGO' );");

c.execute("UPDATE tb_fruta SET nome = 'LIMAO' WHERE id = 2;");
c.execute("UPDATE tb_fruta SET nome = 'ABACAXI' WHERE id = 6;");

c.execute("DELETE FROM tb_fruta WHERE id = 3;");
c.execute("DELETE FROM tb_fruta WHERE nome = 'UVA';");

conn.commit()
conn.close()

Testing:

$ sqlite3 foobar.db 
SQLite version 3.7.17 2013-05-20 00:56:22
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> SELECT * FROM tb_fruta;
1|BANANA
2|LIMAO
4|MACA
6|ABACAXI
