import os
import sys
from mutagen.mp4 import MP4, MP4Cover
from mutagen.id3 import APIC, ID3

def change_mp3_cover(file_path:str, cover_path:str):
    music = ID3(file_path) # 加载音乐文件
    music.delall('APIC')  # 删除原有封面解析帧
    print("delete origin cover")
    music.save()
    if cover_path.endswith('png'):
        print('add new png cover')
        with open(cover_path, 'rb') as albumart:
            music.add(
                APIC(
                    encoding=3,
                    mime='image/png',
                    type=3, desc=u'Cover',
                    data=albumart.read()
                )
            )
    else:
        print('add new jpeg cover')
        with open(cover_path, 'rb') as albumart:
            music.add(APIC(
                encoding=3,
                mime='image/jpeg',
                type=3, desc=u'Cover',
                data=albumart.read()
            ))    
    print('done')       
    music.save(v2_version=3)



if __name__ == '__main__':
    file_path = './your_music.mp3' # 要修改封面的音乐文件
    cover_path = './your_cover.png' # 使用的封面
    change_mp3_cover(file_path, cover_path)

效果

添加前:

结果：

Error: Doesn’t start with an ID3 tag

当出现如下报错时，先向MP3文件中添加一些属性

1
mutagen.id3._util.ID3NoHeaderError: './547085557.mp3' doesn't start with an ID3 tag

之后正常运行程序即可
