参考以下代码，一看就懂：

    1. # need python3
    2. from mutagen.easyid3 import EasyID3
    3. import os
    5. basedir = os.path.abspath(os.path.dirname(__file__))
    6. # print(basedir)
    8. def process(file_dir):   
    9.     L=[]   
    10.     for root, dirs, files in os.walk(file_dir):  
    11.         for file in files:  
    12.             # print(file)
    13.             if file.find(".mp3") > 0:
    14.                 print(file)
    15.                 arr = file.rsplit('.',1)
    16.                 audio = EasyID3(basedir+"/"+file)
    17.                 audio['artist'] = u"Me"
    18.                 audio.save() 
    21. process(basedir)
    24. # 其他用法
    25. # audio = EasyID3("example.mp3")
    26. # audio['title'] = u"Example Title"
    27. # audio['artist'] = u"Me"
    28. # audio['album'] = u"My album"
    29. # audio['composer'] = u"" # clear
    30. # audio.save()
    34. # import eyed3
    35. # audiofile = eyed3.load("song.mp3")
    36. # audiofile.tag.artist = u"Nobunny"
    37. # audiofile.tag.album = u"Love Visions"
    38. # audiofile.tag.title = u"I Am a Girlfriend"
    39. # audiofile.tag.track_num = 4
    40. # audiofile.tag.save()
