Thank you @cvp for all your help and @Phuket2 for filtering code.
I have put up the fully working version below.
I use this to order a lot of books for our bookstore.
I have the csv data file with a few thousand records of book title and book author.
import ui
items = [
['Pretty Woman', 'Julia Roberts'],
['Seven Year Itch', 'Marilyn Monroe'],
['Casablanca' , 'Ingrid Bergman'],
['Roman Holiday','Audrey Hepburn'],
['African Queen','Katherine Hepburn'],
['Out Of Africa','Meryl Streep'],
['Cleopatra','Elizabeth Taylor'],
['Titanic','Kate Winslet'],
['Apartment','Shirley MacLaine'],
['West Side Story','Natalie Wood'],
['Rear Window','Grace Kelly'],
['Pillow Talk','Doris Day'],
['Sound Of Music','Julie Andrews'],
['Love Story','Ali McGraw'],
['You Got Mail','Meg Ryan'],
['Clueless','Alicia Silverstone'],
['Great Gatsby','Mia Farrow'],
['Mask','Cameron Diaz'],
['Kill Bill', 'Uma Thurman'],
]
