This assignment helps you practice with “classes”. Read the book for guidance: Chapter 15 and Chapter 17.I’ve written another version of the album database (from Homework 5), this time using a class to represent an album. The class keeps track of the album’s artist, title, year, and a list of ratings. Your task is to write this class. The rest of the code should remain unchanged.Here is the code. Refer to the comments in the code for an explanation of your task. Also see the expected output below in the word document:your solution should reproduce this output.

import os

Your class definition goes here. Name the class Album.
Notice how the class is used in the code below
(which functions exist, etc.).
You must not create any new variables outside the class;
the purpose is to create a class only, no extra code.
Make sure your code recreates the example output below.
def get_rating(album):
rating = float(input(“Enter rating: “))
album.add_rating(rating)
def get_album():
artist = input(“Artist: “)
title = input(“Album title: “)
year = int(input(“Album year: “))
album = Album(artist, title, year)
get_rating(album)
return album
if os.path.exists(“albumsHW08.pkl”):
with open(“albumsHW08.pkl”, “rb”) as f:
albums = pickle.load(f)
else:
albums = []
while True:
print(“Albums in database:”)
for i in range(len(albums)):
print(“===== %d =====” % i)
albums[i].print()
print()
print(“Type new to enter a new album, type rate to rate an
album.”)
answer = input(“Command: “)
if answer == “new”:
albums.append(get_album())
elif answer == “rate”:
idx = int(input(“Enter album # from list above: “))
if idx < 0 or idx >= len(albums):
print(“Bad #”)
else:
get_rating(albums[idx])
else:
print(“Exiting…”)
break
with open(“albumsHW08.pkl”, “wb”) as f:
pickle.dump(albums, f)
