use python to write a function read_books(file_name) which takes in the name of a file as parameter and returns a list. Each list item will itself be a list of two items: title and author. Note: The index of the book in this list is the book's index within the user's ratings.

The function should return None if the file could not be read. Otherwise, it should return a list filled with data from that file. Note: if the file is empty, you should return an empty list.

books.txt

The data file containing the books contains a single book per line. Each entry has the authors name and title of the book separated by commas.
