Question

Create two classes.

Song. Should include the name of the song and the artist

Playlist. Should include a list of song objects from the above class, a title for the list and a description of the list. Specific method requirements below.

Functionality

You should be able to print both a song and a playlist. Formatting should follow the below examples EXACTLY. I should be able to print a so11ng or a playlist by calling the standard python print function.

Format for printing a song should be	Format for printing a play list should be
Title: <song title> Artist: <artist> Example. Title: Bad Guy Artist: Billie Eilish	Playlist: <playlist title> Description: <playlist description> Songs: <title1> <title2> . <titleN> Example. Playlist: Country Gooderns Description: Classic country songs Songs: Coal Miner’s Daughter Walk the Line Friends in Low Places Stand by your Man

The play list class should allow adding songs through an addSong method. Duplicate song names are not allowed and should result in an error message back to the user. Songs with the same title but different case would be considered duplicates. Walk The Line would be considered a duplicate of WALK THE line.

The play list class should allow searching to see if a song exists through a songFound method. This search can be done on an exact match of the title (upper or lower case allowed). If I searched for walk THE Line in the above list, it would find a match. Result should be returned as a Boolean.

The play list class should allow randomizing the order of the songs in the list through a shuffleList method. Songs would normally be included in the order they were added. If I call the randomize process, the playlist should be shuffled into a random order of songs.

Answer 1

I have created all the classes in a single file and included main method to test the methods in classes. Please feel free to change the main method in any way required

Below are the screenshots of the file:

Below is the code for the same:

from random import shuffle


class Song:
    def __init__(self, name, artist):
        self.name = name
        self.artist = artist

    # Method to print a Song
    def print(self):
        print("Title: ", self.name)
        print("Artist: ", self.artist)


class Playlist:
    def __init__(self, title, desc):
        self.title = title
        self.desc = desc
        self.songs = []

    # Method to add a Song
    def addSong(self, newSong):
        # Checking for duplicate songs even if the case is different
        for song in self.songs:
            if song.name.upper() == newSong.name.upper():
                return "Error: Song with title '" + newSong.name + "' already exists"

        # If it is not a duplicate add to the list
        self.songs.append(newSong)
        return "Successfully added '" + newSong.name + "'"

    # Method to search a song
    def songFound(self, songTitle):
        for song in self.songs:
            if song.name.upper() == songTitle.upper():
                return True
        return False

    # Method to shuffle the list of songs to change their order
    def shuffleList(self):
        shuffle(self.songs)

    # Method to print the Playlist
    def print(self):
        print("Playlist: ", self.title)
        print("Description: ", self.desc)
        print("Songs:")
        for song in self.songs:
            print(song.name)


def main():
    # Creating Song objects
    s1 = Song("Bad Guy", "Billie Eilish")
    s2 = Song("Coal Miner's Daughter", "Billie Donald")
    s3 = Song("Walk the Line", "Cathy")
    s4 = Song("Friends in low places", "John")

    # Creating a Playlist
    p1 = Playlist("Country Gooderns", "Classic Country Songs")

    # Adding songs to the playlist
    print(p1.addSong(s1))
    print(p1.addSong(s2))
    print(p1.addSong(s3))
    print(p1.addSong(s4))
    # Adding a song which already exists
    print(p1.addSong(Song("bad guy", "Bowden")))

    # Printing the Playlist
    p1.print()

    # Finding the song in the Playlist
    print(p1.songFound("Bad Guy"))
    # Shuffling the songs
    p1.shuffleList()
    # Printing the sings after shuffling
    p1.print()


if __name__ == "__main__":
    main()
