これまで私がこれまで持っていたことです。これは進行中のPythonプロジェクトですが、今は私が困惑しています。ジャスティン・ティンバーレイクがユーザーによって「artistsearch」と入力された場合のように、アーティストが検索しようとしています。インデックスをプルダウンして、曲リストのインデックスと一致させてその情報をユーザーに表示できるようにします。

私がディスプレイを実行したときに名前が表示されても、ジャス​​ティン・ティンバーレイクがリストの価値でない理由を判断するのに役立つものは、すべてのアーティストオプションを高く評価します。

また、リストインデックスを一致させるために正しい方向を指し示すことも同様に優れています。これはtunes.txtの例である：

Alicia Keys 
No One 
As I Am 
R&B/Soul;Syl tunes 

Everything But the Girl 
Missing 
Amplified Heart 
Alternative;Syl tunes 

Gathering Field 
Lost In America 
Lost In America 
Rock 

Ellie Goulding 
Burn 
Halcyon 
Pop;Road tunes 

Justin Timberlake 
Mirrors 
Mirrors (Radio Edit) - Single 
Pop;Syl tunes

私はあなたが保存するデータの特定のクラスを作成し、そのようなクラスをインスタンス化したオブジェクトのリストを作成すべきだと思う：

class Song(): 
    """Class to store the attributes for each song""" 
    def __init__ (self): 
     self.artist = "" 
     self.song = "" 
     self.album = "" 
     self.genre = "" 

# List to store all the Song objects 
songs_list = [] 

f = open('C:\\Users\\user.name\\Desktop\\tunes.txt','r') 
index=0 
for line in f: 
    # Instantiate an empty Song object 
    s = Song() 
    if index == 0: 
     s.artist = line 
     index=index+1 
    elif index == 1: 
     s.song = line 
     index = index + 1 
    elif index == 2: 
     s.album = line 
     index = index + 1 
    elif index == 3: 
     s.genre = line 
     index = index+1 
    elif index == 4: 
     index = 0 
    songs_list.append(s)
