Python-错误：AudioFileOpen失败（'wht？'）'是什么意思？

Question

我试图运行此代码，但它导致以下错误：错误：AudioFileOpen失败（'wht？'）。因此，这里是我的代码，它是在Mac上并与MP3文件的文件夹运行，如果这是任何帮助：

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/') 

任何帮助，欢迎和极大的感谢

看一看这（从你的问题）：

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

并记住music包含：（文件名列表如"Adele - Hello.mp3"）。当你把它们传递给afplay你不告诉它在寻找哪个目录（请注意，该错误信息不会从Python中来，而是从自身afplay;如见this other question where the same command is called from C。）

尝试使用os.path.join()包括该目录，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)) 

这样afplay会收到类似"/Users/you/Desktop/Music/Adele - Hello.mp3"的绝对路径。
