Python-錯誤：AudioFileOpen失敗（'wht？'）'是什麼意思？

Question

我試圖運行此代碼，但它導致以下錯誤：錯誤：AudioFileOpen失敗（'wht？'）。因此，這裏是我的代碼，它是在Mac上並與MP3文件的文件夾運行，如果這是任何幫助：

import os 
def randomShuffleSongFromFolder(folderPath): 
    try: 
     music = os.listdir(folderPath) 
    except: 
     print('Error-Music folder not found') 
     exit() 
    random.shuffle(music) 
    music.remove('.DS_Store') 
    print(folderPath) 
    print(music) 
    for song in music: 
     os.system('afplay "' + song + '"') 
if __name__ == '__main__': 
    print(os.listdir('/Users/isaac_lims_macbook_air/Desktop/davidMusic')) 
randomShuffleSongFromFolder('/Users/isaac_lims_macbook_air/Desktop/MusicExample/') 

任何幫助，歡迎和極大的感謝

Answer 1

看一看這（從你的問題）：

for song in music: 
    os.system('afplay "' + song + '"') 

並記住music包含：（文件名列表如"Adele - Hello.mp3"）。當你把它們傳遞給afplay你不告訴它在尋找哪個目錄（請注意，該錯誤信息不會從Python中來，而是從自身afplay;如見this other question where the same command is called from C。）

嘗試使用os.path.join()包括該目錄，例如

import os.path 

# Assuming folderPath is being passed into the containing function as above 
for song in music: 
    songPath = os.path.join(folderPath, song) 
    os.system('afplay "{}"'.format(songPath)) 

這樣afplay會收到類似"/Users/you/Desktop/Music/Adele - Hello.mp3"的絕對路徑。
