I ve used mutagen to edit tags in media files before   The nice thing about mutagen is that it can handle other formats  such as mp4  FLAC etc   I ve written several scripts with a lot of success using this API

I looked the above answers and found out that they are not good for my project because of licensing problems with GPL   And I found out this  PyID3Lib  while that particular python binding release date is old  it uses the ID3Lib  which itself is up to date   Notable to mention is that both are LGPL  and are good to go

I would suggest mp3-tagger  Best thing about this is it is distributed under MIT License and supports all the required attributes   - artist  - album  - song  - track  - comment  - year  - genre  - band  - composer  - copyright  - url  - publisher    Example   from mp3 tagger import MP3File    Create MP3File instance  mp3   MP3File  File Name mp3      Get all tags  tags   mp3 get tags   print tags    It supports set  get  update and delete attributes of mp3 files

What you re after is the ID3 module   It s very simple and will give you exactly what you need   Just copy the ID3 py file into your site-packages directory and you ll be able to do something like the following   from ID3 import   try    id3info   ID3  file mp3     print id3info     Change the tags   id3info  TITLE      Green Eggs and Ham    id3info  ARTIST      Dr  Seuss    for k  v in id3info items        print k       v except InvalidTagError  message    print  Invalid ID3 tag    message

It can depend on exactly what you want to do in addition to reading the metadata  If it is just simply the bitrate   name etc  that you need  and nothing else  something lightweight is probably best   If you re manipulating the mp3 past that PyMedia may be suitable   There are quite a few  whatever you do get  make sure and test it out on plenty of sample media  There are a few different versions of ID3 tags in particular  so make sure it s not too out of date    Personally I ve used this small MP3Info class with luck  It is quite old though   http   www omniscia org  vivake python MP3Info py

The first answer that uses eyed3 is outdated so here is an updated version of it   Reading tags from an mp3 file    import eyed3   audiofile   eyed3 load  some file mp3    print audiofile tag artist   print audiofile tag album   print audiofile tag album artist   print audiofile tag title   print audiofile tag track num    An example from the website to modify tags    import eyed3   audiofile   eyed3 load  some file mp3    audiofile tag artist   u Integrity   audiofile tag album   u Humanity Is The Devil   audiofile tag album artist   u Integrity   audiofile tag title   u Hollow   audiofile tag track num   2   An issue I encountered while trying to use eyed3 for the first time had to do with an import error of libmagic even though it was installed  To fix this install the magic-bin whl from here

I used eyeD3 the other day with a lot of success   I found that it could add artwork to the ID3 tag which the other modules I looked at couldn t   You ll have to install using pip or download the tar and execute python setup py install from the source folder     Relevant examples from the website are below   Reading the contents of an mp3 file containing either v1 or v2 tag info    import eyeD3  tag   eyeD3 Tag    tag link   some file mp3    print tag getArtist    print tag getAlbum    print tag getTitle     Read an mp3 file  track length  bitrate  etc   and access it s tag   if eyeD3 isMp3File f        audioFile   eyeD3 Mp3AudioFile f       tag   audioFile getTag     Specific tag versions can be selected    tag link   some file mp3   eyeD3 ID3 V2   tag link   some file mp3   eyeD3 ID3 V1   tag link   some file mp3   eyeD3 ID3 ANY VERSION     The default    Or you can iterate over the raw frames    tag   eyeD3 Tag    tag link   some file mp3    for frame in tag frames      print frame   Once a tag is linked to a file it can be modified and saved    tag setArtist u Cro-Mags    tag setAlbum u Age of Quarrel    tag update     If the tag linked in was v2 and you d like to save it as v1    tag update eyeD3 ID3 V1 1    Read in a tag and remove it from the file    tag link   some file mp3    tag remove    tag update     Add a new tag    tag   eyeD3 Tag    tag link   some file mp3        no tag in this file  link returned False  tag header setVersion eyeD3 ID3 V2 3   tag setArtist  Fugazi    tag update

After trying the simple pip install route for eyeD3  pytaglib  and ID3 modules recommended here  I found this fourth option was the only one to work  The rest had import errors with missing dependencies in C   or something magic or some other library that pip missed  So go with this one for basic reading of ID3 tags  all versions    https   pypi python org pypi tinytag 0 18 0  from tinytag import TinyTag tag   TinyTag get   some music mp3     List of possible attributes you can get with TinyTag   tag album           album as string tag albumartist     album artist as string tag artist          artist name as string tag audio offset    number of bytes before audio data begins tag bitrate         bitrate in kBits s tag disc            disc number tag disc total      the total number of discs tag duration        duration of the song in seconds tag filesize        file size in bytes tag genre           genre as string tag samplerate      samples per second tag title           title of the song tag track           track number as string tag track total     total number of tracks as string tag year            year or data as string   It was tiny and self-contained  as advertised

After some initial research I thought songdetails might fit my use case  but it doesn t handle  m4b files   Mutagen does   Note that while some have  reasonably  taken issue with Mutagen s surfacing of format-native keys  that vary from format to format  TIT2 for mp3  title for ogg   xa9nam for mp4  Title for WMA etc    mutagen File   has a  new   easy True parameter that provides EasyMP3 EasyID3 tags  which have a consistent  albeit limited  set of keys   I ve only done limited testing so far  but the common keys  like album  artist  albumartist  genre  tracknumber  discnumber  etc  are all present and identical for  mb4 and  mp3 files when using easy True  making it very convenient for my purposes

easiest method is songdetails   for read data import songdetails song   songdetails scan  quot blah mp3 quot   if song is not None      print song artist  similarly for edit import songdetails song   songdetails scan  quot blah mp3 quot   if song is not None      song artist   u quot The Great Blah quot      song save    Don t forget to add u before name until you know chinese language  u can read and edit in bulk using python glob module ex  import glob songs   glob glob          script should be in directory of songs  for song in songs        do the above work

A problem with eyed3 is that it will throw NotImplementedError  Unable to write ID3 v2 2   for common MP3 files   In my experience  the mutagen class EasyID3 works more reliably  Example   from mutagen easyid3 import EasyID3  audio   EasyID3  example mp3   audio  title     u Example Title  audio  artist     u Me  audio  album     u My album  audio  composer     u     clear audio save     All other tags can be accessed this way and saved  which will serve most purposes  More information can be found in the Mutagen Tutorial
