Python编程修改MP3文件名称的方法
本文实例讲述了Python编程修改MP3文件名称的方法。分享给大家供大家参考,具体如下:
最近刚刚开始学习Python,顺便锻炼思维写的一个小函数,专门用来修改那些网上下载的mp3歌曲后名称不正确时候,使用该函数,使用方法
ModifyMp3FileInfo(r'E:/音乐/12345.mp3')
Python代码:
#!修改下载的Mp3文件名称为正确的Mp3文件 def ModifyMp3FileInfo(filename): mp3Id3V1 = { "tag":{"valuepos":(0,3),"value":""}, "SongName":{"valuepos":(3,33),"value":""}, "SongPeople":{"valuepos":(33,63),"value":""}, "Zj":{"valuepos":(63,93),"value":""}, "Year":{"valuepos":(93,97),"value":""}, "Bak":{"valuepos":(97,125),"value":""} } try: f = open(filename,'rb') f.seek(-128,2) sdata = f.read(3) if sdata == 'TAG': f.seek(-128,2) sdata = f.read(128) for tag,subitem in mp3Id3V1.items(): subitem["value"] = sdata[subitem["valuepos"][0]:subitem["valuepos"][1]].replace('/00','').strip() print '%s='%tag,'%s'%subitem["value"],'/n' f.close() import os if mp3Id3V1["SongName"]["value"]!='': test = [os.path.dirname(filename),'//'] test.append(mp3Id3V1["SongName"]["value"]) test.append('.mp3') newfilename = ''.join(test) print newfilename if os.path.exists(newfilename): test = ['Filename ',newfilename,' Has Existed'] print ''.join(test) else: try: os.rename(filename,newfilename) except WindowsError,e: if e.winerror: print 'Modify filename failed ,maybe the file is inuse' else: print 'UnKnown error' else: print 'Is not a MP3 file' except IOError: print 'Open file failed'
