PYTHON

Extend the program such that a user can add artists, albums, and songs to the library. First, add a command that adds an artist name to the music dictionary. Then add commands for adding albums and songs. Take care to check that an artist exists in the dictionary before adding an album, and that an album exists before adding a song.

music = {
'Pink Floyd': {
'The Dark Side of the Moon': {
'songs': [ 'Speak to Me', 'Breathe', 'On the Run', 'Money'],
'year': 1973,
'platinum': True
},
'The Wall': {
'songs': [ 'Another Brick in the Wall', 'Mother', 'Hey you'],
'year': 1979,
'platinum': True
}
},
'Justin Bieber': {
'My World':{
'songs': ['One Time', 'Bigger', 'Love Me'],
'year': 2010,
'platinum': True
}
}
}

music = {}
valid = False;

while(valid == False):
   artist = input ("Please enter artist name:")
   if(artist not in music):
       print(" Key not exist");
       music[artist] = {}
   #Now ask other details
   album = input ("Please enter album name:")

       print(" album not exist");
       music[artist][album] = {}
   print("Add song(s) in new line (Exit to stop)")
   song = ""
   if("songs" not in music[artist][album]):
       music[artist][album]["songs"] = []
       songarr = (music[artist][album]["songs"])
   while(song != "Exit" and song != "exit"):
       song = input ("Please enter song name:")
       if((song != "Exit" and song != "exit") and song not in songarr):
           songarr.append(song)

   music[artist][album]["songs"] = songarr
  
   year = input("Enter year of album")
   music[artist][album]["year"] = year
  
   platinum = input("Is it Platinum ? (y/n)")
  
   if(platinum == "y"):
       music[artist][album]["platinum"] = True
   else:
       music[artist][album]["platinum"] = False
   print(music)
  
   uinput = input("Are you continuing (y/n) ?")
