How do I print certain data from a CSV file through user input

Question

I created a CSV file that stores a book, its author and the year the book released, through user input. I want to now ask the user to choose an author and the program should display all the books by that author, but I'm not sure how to do this

Here is my code so far:

import csv

amount = int(input("How many records would you like to store: "))
count = 0

with open("Books.csv", "w", newline="") as file:
    writer = csv.writer(file)
    writer.writerow(["", "Book", "Author", "Year released"])

while count < amount:
    count += 1

    book = input("Enter a book: ")
    author = input("Enter it's Author: ")
    year = input("Enter the year it released: ")

    headers = [count, book, author, year]
    with open("Books.csv", 'a') as f:
        writer = csv.writer(f)
        writer.writerow(headers)

Answer 1

This should do.

Example contents of Books.csv

,Book,Author,Year released
0,1984,G. Orwell,1949
1,Brave New World,A. Huxley,1932
2,Johnny Got His Gun,D. Trumbo,1939

The code

import csv

# getting author and book column indexes in the csv
COLUMNS = ["", "Book", "Author", "Year released"]    # first column is the book no.
AUTHOR_COLUMN_INDEX = COLUMNS.index("Author")
BOOK_COLUMN_INDEX = COLUMNS.index("Book")

author = input("Enter the name of an author: ")

with open('Books.csv', 'r', newline='') as f:
    for line in csv.reader(f):
        if len(line) == len(COLUMNS):   # if empty line or invalid line
            if line[AUTHOR_COLUMN_INDEX] == author:
                print(line[BOOK_COLUMN_INDEX])

When the code is run:

Enter the name of an author: A. Huxley
Brave New World
