Here is the code using python 3 import as ET The database is modified by adding genre.
If name is None or artist is None or genre is None or album is None: Here is the complete code works for your situation: import as ET ( name, album_id, genre_id, length, rating, count ) ) (title, album_id, genre_id, len, rating, count) VALUES ( ?, ? )''', ( album, artist_id ) )Ĭur.execute('SELECT id FROM Album WHERE title = ? ', (album, ))Ĭur.execute('''INSERT OR IGNORE INTO Genre (name)Ĭur.execute('SELECT id FROM Genre WHERE name = ?
