Do not use AI! You can schedule to try again if you have a bad grade!
You are building a music playlist system. Write a function named 'manage_playlist' which receives 3 paramenters: a
list of song names, a new song name to be added to the end of the playlist, and a song name to be searched in the
playlist. It should return the index of the searched song in the updated playlist (or None if the song is not found).
Example:
playlist = ['Dream On', 'Bohemian Rhapsody', 'Stairway to Heaven']
print(manage_playlist(playlist, 'Hotel California', 'Bohemian Rhapsody')) # Output: 1
print(playlist) # Output: ['Dream On', 'Bohemian Rhapsody', 'Stairway to Heaven', 'Hotel California']
playlist = ['Imagine', 'Confortably Numb']
print(manage_playlist(playlist, 'Wish You Were Here', 'Wish You Were Here')) # Output: 2
print(playlist) # Output: ['Imagine', 'Confortably Numb', 'Wish You Were Here']
playlist = ['Imagine', 'Confortably Numb']
print(manage_playlist(playlist, 'Wish You Were Here', 'Smoking on the Water')) # Output: None
print(playlist) # Output: ['Imagine', 'Confortably Numb', 'Wish You Were Here']
'''
def manage_playlist(playlist, new_song, search_song):
playlist.append(new_song)
for i in range(len(playlist)):
if playlist[i] == search_song:
return i
return None
playlist = ['Dream On', 'Bohemian Rhapsody', 'Stairway to Heaven']
print(manage_playlist(playlist, 'Hotel California', 'Bohemian Rhapsody')) # Output: 1
print(playlist) # Output: ['Dream On', 'Bohemian Rhapsody', 'Stairway to Heaven', 'Hotel California']
playlist = ['Imagine', 'Confortably Numb']
print(manage_playlist(playlist, 'Wish You Were Here', 'Wish You Were Here')) # Output: 2
print(playlist) # Output: ['Imagine', 'Confortably Numb', 'Wish You Were Here']
playlist = ['Imagine', 'Confortably Numb']
print(manage_playlist(playlist, 'Wish You Were Here', 'Smoking on the Water')) # Output: None
print(playlist) # Output: ['Imagine', 'Confortably Numb', 'Wish You Were Here']
