Explanation / Answer
NOTE: I have the original file itunes.txt so i have written the script based on that. Also i have completed 6 questions in the list you gave and left one because as per Chegg policy we are expected to complete first 4 questions.
Code:

if __name__=='__main__':
fp = open("itunes.txt", "r");
d_artist = d_album = d_genre = {}
for line in fp:
lst = line.split(' ')
#artist, album, genre = lst[1], lst[3], lst[9]
artist, album, genre = lst[1], lst[3], lst[17]
if artist == 'Artist':
continue
d_artist.setdefault(artist, list()). append(lst)
d_album.setdefault(album,list()).append(lst)

f= open("itunes.txt", "r+")
d = f.readlines()
f.seek(0)
for i in d:
