How Python writes data to a MP3 file

The example in this article describes how Python writes data to a MP3 file. Share to everyone for your reference. The specific analysis is as follows:

The correct name of the Mp3 file is corrected by Mp3 the data in the ID3v1 data section, but sometimes the data in the data break is empty, so writing a function that modifies the data of the ID3v1 data segment is also an exercise.

How to use:

writemp3header[Songname] = ' Test song name ' writemp3header[songpeople] = ' no idle ' writemp3header[Zhuanji] = ' album ' writemp3header[Y Ear] = ' writemp3header[Bak] = ' Memo test ' Setmp3header (R ' E:\test.mp3 ')

The Python code is as follows:

Writemp3header = {   "songname": "",   "songpeople": "",   "Zhuanji": "",   "Year": "",   "Bak": "   } def setmp3header (mp3file):   mp3id3v1 = {         "songname": -125,     "songpeople": -95,     "Zhuanji": -65,     " Year ": -35,     " Bak ": -31     }   tags = [' songname ', ' songpeople ', ' Zhuanji ', ' bak ']   f = open (Mp3file, ' r+ ')   Try:     f.seek ( -128,2)     try:       tempstr = F.read (3)       if TempStr = = ' TAG ': for         Tag,startpos in Mp3id3v1.items ():           if writemp3header[tag]! = ":             f.seek (startpos,2)             if tag in tags:               if len ( Writemp3header[tag]) >:                  f.write (writemp3header[tag][:30])               else:                 f.write (Writemp3header[tag] )             Print Startpos,tag,writemp3header[tag]       else:         print ' is not a mp3file '     except IOError:       print ' read error '   finally:     f.close ()
