使用 python 从 mp3 文件编辑标签

Question

我正在尝试从 mp3 或 flac 文件中打印出每个标签，然后使用 python 对其进行编辑，但只有一些标签具有数据显示，例如：艺术家、标题、专辑、日期。但并不是每首歌都会出现相同的标签。

这是我制作的代码。

import os
import mutagen.easyid3
import mutagen.flac     ## make reading flac file possible

def main():
    print("start")
    for root, dirs, files in os.walk("C:\muziek\muziekfiles"):  ## where to look for songs
        for name in files:
            if name.endswith((".mp3", ".flac")):
                print()
                file_path = os.path.join(root +"\\" + name)
                if name.endswith(".flac"):
                    audio = mutagen.flac.FLAC(file_path)
                else:
                    audio = mutagen.easyid3.EasyID3(file_path)
                for key in audio:
                    if key == "padding": ## if there were to be padding
                        if audio[key] is None:
                            print(f"{key}: no_new_padding")
                        else:
                            print(f"{key}: {len(audio[key])}")
                    else:
                        print(f"{key}: {audio[key]}")

                ## asks user
                choice = input("Do you want to change a tag, y/n: ")
                if choice.lower() == "y":
                    tag_key = input("which one, eg: artist, title: ")  ## choose which tag
                    tag_value = input("new value: ") ## give new value

                    ## stores new values and then saves itn
                    audio[tag_key] = tag_value
                    audio.save()
                    ## if there isn't any padding
                if "padding" not in audio:
                    print("padding: None")

if __name__ == "__main__":
    main()

我也试图找到填充，但结果是：填充：无，每首歌曲一次。我不知道这是否取决于我从哪里下载歌曲，但我怀疑它没有填充

这就是我得到的：我已经更改了一些标签来测试我的代码
