DAT/210 Week 5 Python 6.23: Python insert/update sqlite3 datafiles

Given is a Python program that connects to a sqlite database and has one table called writers with two columns:
• name – the name of a writer
• num – the number of works the writer has written

The writers table originally has the following data
name, num
Jane Austen,6
Charles Dickens,20
Ernest Hemingway,9
Jack Kerouac,22
F. Scott Fitzgerald,8
Mary Shelley,7
Charlotte Bronte,5
Mark Twain,11
Agatha Christie,73
Ian Flemming,14
J.K. Rowling,14
Stephen King,54
Oscar Wilde,1
Update the Python program to ask the user if they want to update entries or add new entries. If the name entered already exists in the writers table then the database record is updated, overwriting the original contents. If the name does not exist in the writers table, then add a new record with the writers name and number of works. The following TODO sections must be completed.
• Check if a writer exists in the writers table
• If the writer exists in the table, locate an entry to be updated by writers name and update the writer’s value for num
• If the writer does not exist in the table, add a new entry in the writers table and provide the value for name and num

Ex if the input is:
y
J.K. Rowling
30
y
Elton John
y
62
n
The output is:
(ID, Name, Num)
(1, ‘Jane Austen’, 6)
(2, ‘Charles Dickens’, 20)
(3, ‘Ernest Hemingway’, 9)
(4, ‘Jack Kerouac’, 22)
(5, ‘F. Scott Fitzgerald’, 8)
(6, ‘Mary Shelley’, 7)
(7, ‘Charlotte Bronte’, 5)
(8, ‘Mark Twain’, 11)
(9, ‘Agatha Christie’, 73)
(10, ‘Ian Flemming’, 14)
(11, ‘J.K. Rowling’, 30)
(12, ‘Stephen King’, 54)
(13, ‘Oscar Wilde’, 1)
(14, ‘Elton John’, 62)
