Sqlite3 Python 2.7 sqlite3.OperationalError syntax error

import sqlite3
import codecs

sqlite3.connect("test.db")
db.execute("""CREATE TABLE IF NOT EXISTS STATIONS
       (StationUID INT PRIMARY KEY     NOT NULL,
       StationNumber           TEXT    NOT NULL,
       StationName             TEXT    NOT NULL,
       StationLongitude        REAL    NOT NULL,
       StationAltitude         REAL    NOT NULL);""")

print "Created Table STATIONS successfully"
cr = db.cursor()
name = "b"
station_number = "0123"
longitude = 13.4
altitude = 34.4
cr.execute("INSERT INTO STATIONS VALUES", (None, station_number, name, longitude, altitude))
db.commit()

It throws sqlite3.OperationalError: near "VALUES": syntax error, but i don't understand why, because it is the same syntax i found in the example.
