try:
    connection = mysql.connector.connect(host='localhost',
                                         database='Electronics',
                                         user='pynative',
                                         password='pynative@#29')

    mySql_insert_query = """INSERT INTO Laptop (Id, Name, Price, Purchase_date) 
                           VALUES (%s, %s, %s, %s) """

    records_to_insert = [(4, 'HP Pavilion Power', 1999, '2019-01-11'),

    cursor = connection.cursor()
    cursor.executemany(mySql_insert_query, records_to_insert)
    connection.commit()
    print(cursor.rowcount, "Record inserted successfully into Laptop table")

except mysql.connector.Error as error:
    print("Failed to insert record into MySQL table {}".format(error))

        cursor.close()
        connection.close()
        print("MySQL connection is closed")
