使用 EasyID3 编写 ID3 标签

Question

我正在编写一个使用诱变剂更新 .mp3 文件中的元数据信息的脚本。
评论标签好像有问题

到目前为止，这是我的代码

import  mutagen
from mutagen.easyid3 import EasyID3

path = 'song.mp3'
try:
    tag = EasyID3(path)
except:
    tag = mutagen.File(path, easy=True)
    tag.add_tags()

tag['genre'] = 'mygenre'
tag['artist'] = 'myartist'
tag['title'] = 'mytitle'
tag['date'] = '1000'
tag['album'] = 'myalbum'
tag['albumartist'] = 'myalbumartist'
tag['tracknumber'] = 'mytracknumber'
tag['discnumber'] = 'mydiscnumber'
tag.save(v2_version=3)

这对我来说很好，但是当我添加

tag['comment'] = 'mycomment'

我收到以下错误

mutagen.easyid3.EasyID3KeyError: "'comment' is not a valid key"

Answer 1

>>> import pprint
>>> from mutagen.easyid3 import EasyID3
>>> print EasyID3.valid_keys.keys()
>>> pprint.pprint(EasyID3.valid_keys.keys())

似乎 comment 确实不是有效密钥。不怕，好像是you can define your own! Combining that with this document，好像我们需要的frameid就叫COMM。因此，添加一个 EasyID3.RegisterTextKey('comment', 'COMM') 应该（可能）让你做你需要的。 :)
