Using user input to find information in a Mysql database

import MySQLdb

user_input = raw_input("Please enter barcode and press Enter button: ")

db = MySQLdb.connect(passwd="moonpie",db="thangs")
mycursor = db.cursor()
mycursor.execute("""SELECT name, price FROM Product
                 WHERE barcode = %s""", (user_input,))

# calls fetchone until None is returned (no more rows)
for row in iter(mycursor.fetchone, None):
    print row

product = session.query(Product).filter(Product.barcode == user_input).scalar()
print product.name, product.price
