如何在python语音识别器中启动mp4文件？

Question

我正在根据youtube教程创建python语音助手。不幸的是，视频创建者有一个windows操作系统。所以他使用OS模块中的startfile。但这在ubuntu中不起作用。以下是视频制作者使用的代码：

elif 'play music' in query:     
        music_dir = '/home/thilak/Music'
        songs = os.listdir(music_dir)
        print(songs)
        os.startfile(os.path.join(music_dir, songs[0]))

但这不适合我，所以我用了这个：

elif 'play music' in query:     
        music_dir = '/home/thilak/Music'
        songs = os.listdir(music_dir)
        print(songs)
        os.system(os.path.join(music_dir, songs[0])) #changing startfile to system

不过，此代码也显示了如下错误消息：

Say that again please...

['Despacito and senorita (copy).mp4', 'Curtis Waters - Stunnin’ (Lyrics) “ I’m a pretty boy,I’m stunning “-YVrha4CjldA.mkv', 'DJ Snake ft. Justin Bieber - Let Me Love You [Lyric Video]-SMs0GnYze34 (copy).mkv', 'Curtis Waters - Stunnin’ (Lyrics) “ I’m a pretty boy,I’m stunning “-YVrha4CjldA (copy).mkv', 'Despacito and senorita.mp4', 'DJ Snake ft.

sh: 1: Syntax error: "(" unexpected

请帮我解决这个问题。谢谢大家!

如前所述，代码是针对windows的，使用ffmpeg的ffplay如何

elif 'play music' in query:     
        music_dir = '/home/thilak/Music'
        songs = os.listdir(music_dir)
        print(songs)
        os.popen('ffplay -nodisp -autoexit "'+os.path.join(music_dir, songs[0])+'" >/dev/null 2>&1')

在使用上述代码之前，请记住使用apt安装ffmpeg

sudo apt-get update
sudo apt-get install ffmpeg
