Answer 1

摘自我不久前制作的用于将歌词嵌入 MP3 文件的脚本：

http://code.activestate.com/recipes/577138-embed-lyrics-into-mp3-files-using-mutagen-uslt-tag/

相关部分是：

from pathlib import Path

from mutagen.mp3 import HeaderNotFoundError
from mutagen.id3 import Encoding, ID3NoHeaderError, ID3, TIT2, TALB, TPE1, TPE2, COMM, TCOM, TCON, TDRC, TRCK

# Read the ID3 tag or create one if not present
audio_path = Path('/path/to/Music/audio.mp3')

with audio_path.open(mode='rb') as fib:
    try:
        tags = ID3(fib)
        print(f'BEFORE:\n\n{tags.pprint()}')

    except (ID3NoHeaderError, HeaderNotFoundError):
        print("Adding ID3 header..")
        tags = ID3(audio_path)

    tags["TIT2"] = TIT2(encoding=Encoding.UTF16BE, text='mutagen Title')
    tags["TALB"] = TALB(encoding=Encoding.UTF16BE, text='mutagen Album Name 2025')
    tags["TPE2"] = TPE2(encoding=Encoding.UTF16BE, text='mutagen Band')
    tags["COMM"] = COMM(encoding=Encoding.UTF16BE, lang='eng', desc='desc', text='mutagen comment')
    tags["TPE1"] = TPE1(encoding=Encoding.UTF16BE, text='mutagen Artist')
    tags["TCOM"] = TCOM(encoding=Encoding.UTF16BE, text='mutagen Composer')
    tags["TCON"] = TCON(encoding=Encoding.UTF16BE, text='mutagen Genre')
    tags["TDRC"] = TDRC(encoding=Encoding.UTF16BE, text='2010')
    tags["TRCK"] = TRCK(encoding=Encoding.UTF16BE, text='track_number')

    tags.save(audio_path)
    print(f'\n\nAFTER:\n\n{tags.pprint()}')

Answer 2

您检查过网络上的示例吗？其中一些应该对您有帮助。

[编辑：]

Mutagen教程非常好，因此没有添加更多信息。
dir() 提供了大部分详细信息。

例子

from mutagen.mp3 import MP3
from mutagen.easyid3 import EasyID3
import mutagen.id3

filename = 'xxx.mp3'

# Example which shows how to automatically add tags to an MP3 using EasyID3

mp3file = MP3(filename, ID3=EasyID3)

try:
    mp3file.add_tags(ID3=EasyID3)
except mutagen.id3.error:
    print("has tags")

mp3file['title'] = 'Newly tagged'
mp3file.save()
print(mp3file.pprint())

Answer 3

一个简单的方法是：

from mutagen.easyid3 import EasyID3
audio = EasyID3(mp3_filename_import)
audio['title'] = "Title"
audio['artist'] = "Artist"
audio['album'] = "Album"
audio['composer'] = "" # empty
audio.save()

如果标签没有出现，则将最后一行更改为：

audio.save(v2_version=3)
