Python3批量修改MP3文件的标签

环境
Python 3.6.8 (tags/v3.6.8:3c6b436a57, Dec 24 2018, 00:16:47) [MSC v.1916 64 bit (AMD64)] on win32
pip3 --version
pip 19.2.3

pip3 install eyed3

借助eyed3模块还实现，执行前需要安装libmagic的DLL.。pip3 install python-magic-bin==0.4.14
eyed3读取文件的时候，发现中文文件名报错，但是改成数字或者英文名正常，所以有个替换文件名的操作。

# -*- coding: utf-8 -*-


import eyed3
import os

import operator


prefix=r".mp3"
path=r"C:\Users\f\Desktop\神奇\后续的"

for eachfile in os.listdir(path):
        length=len(eachfile)

        if operator.eq(prefix,eachfile[length-4:length])==True:


                title=u""+eachfile[0:length-4]
                print(title)
                print(eachfile)
                track_num=eachfile[0:eachfile.find('.')]
                print(track_num)
                
                
                newname=str(track_num)+".mp3"
                os.rename(os.path.join(path,eachfile), os.path.join(path, newname))
                audiofile=eyed3.load(newname)
                audiofile.initTag()
                audiofile.tag.album = u"神奇"
                audiofile.tag.track_num =int(track_num)
                audiofile.tag.title =title
                audiofile.tag.album_artist = u"故事"
                audiofile.tag.save()
                os.rename(os.path.join(path,newname), os.path.join(path, eachfile))
