Python Mutagen add cover for image not working

Question

I am trying to edit mp3 tags with mutagen. Now I have been working on setting tags like title. But APIC is still not working.

My code is:

from mutagen.mp3 import MP3 from mutagen.id3 import ID3, APIC, TT2, TPE1, TRCK, TALB, USLT, error # ID3 info: # APIC: picture # TIT2: title # TPE1: artist # TRCK: track number # TALB: album # USLT: lyric pic_file = 'cover.jpg' # pic file audio = MP3('song.mp3', ID3=ID3) try: audio.add_tags() except: pass audio.tags.add(APIC( encoding=3, mime='image/jpeg', type=3, desc='Cover Picture', data=open(pic_file, encoding='ISO-8859-1').read().encode() )) audio.tags.add(TT2(encoding=3, text='title')) audio.tags.add(TALB(encoding=3, text='album')) #audio.tags.add(TPE1(encoding=3, text=item['artist'].decode('utf-8'))) #audio.tags.add(TRCK(encoding=3, text=str(track_num).decode('utf-8'))) #audio.tags.add(USLT(encoding=3, lang=u'eng', desc=u'desc', text=item['lyric'].decode('utf-8'))) audio.save() ID3('song.mp3').save(v2_version=3) 

How can I make it work?

Thanks:)

Edit: Got it working:

 imagedata = open(pic_file, 'rb').read() id3 = ID3('song.mp3') id3.add(APIC(3, 'image/jpeg', 3, 'Front cover', imagedata)) id3.add(TIT2(encoding=3, text='title')) id3.save(v2_version=3)
