8-8 用户的专辑

1. 项目

在为完成练习 8-7 编写的程序中，编写一个 while 循环，让用户输入一个专辑的歌手和名称。获取这些信息后，使用它们来调用函数 make_album()，并将创建的字典打印出来。

在这个 while 循环中，务必要提供退出途径。

 

2. 代码

def make_album(singer_name, album_name, music_quantity= ''):
    album = {'singer_name': singer_name, 'album_name': album_name}
    if music_quantity:
        album['music_quantity'] = music_quantity
    return  album

while True:
    print("Please input singer's name")
    print("(enter 'q' at any time to quit)")

    sg = input("singer_name: ")
    if sg == 'q':
        break

    al = input("album_name: ")
    if al == 'q':
        break
    album0 = make_album(sg, al)
    print(album0)

    album1 = make_album(sg, al, music_quantity=20)
    print(album1)

　　

3. 执行结果

Please input singer's name
(enter 'q' at any time to quit)
singer_name: kevin
album_name: love
{'singer_name': 'kevin', 'album_name': 'love'}
{'singer_name': 'kevin', 'album_name': 'love', 'music_quantity': 20}
Please input singer's name
(enter 'q' at any time to quit)
