使用python扫描本地音乐并下载歌词
这次这个真的是干货哦，昨晚弄了半晚上，，，，从8点吃完饭就开始写，一直到了快12点才弄好，，，新手，伤不起呀。。。。
先简单的说下吧，百度提供了一个音乐搜索的api，你想百度请求类似于

使用python将歌词嵌入歌曲中
以前一直用的是Google Play Music来作为手机的音乐播放器，可是现在谷歌被墙的这么厉害的，从PC上传到Google Play的音乐在手机上面同步下来的话特麻烦，索性放弃之买了大名鼎鼎的Poweramp播放器，开始使用之后瞬间就被Poweramp强大的功能所吸引住了，不愧是安卓端的音乐播放器的王者！唯美的锁屏界面，强大的均衡器功能等等。唯一美中不足的就是歌词.如果要显示歌词的话必须安装第三方软件，或者是把歌词嵌入到音乐中。所以昨天下班之后就开始研究，所幸最后终于搞定了，先上下效果图
可以看到，效果还是很不错的呢。
好了，废话不多说，下面上程序
首先，必须安装eyed3模块，还有，我所有的歌词都在E:\lrc这个路径中的
import threading import time import datetime import re import os import eyed3 import sys reload(sys) sys.setdefaultencoding('utf8') def getstr(i): if i <10: return "0"+str(i) else: return str(i) musicpath=r'I:\music' lrcpath=r'E:\lrc' def deallrc(str): mystr=re.sub(r'\[\d\d:\d\d.\d\d\]','',str) mystr.replace('\n','') return mystr def checklrcfile(path,timespan): file=open(path,'r') mylrcstr='' #print timespan for line in file.readlines(100): #errorlog(line) if line.find(timespan)>0: return deallrc(line) else: continue return '' def getlrcstr(lrc): mylrcstr='' #print lrc for i in range(00,05): for j in range(00,59): for k in range(00,99): timespan=getstr(i)+":"+getstr(j)+"."+getstr(k) mylrcstr+=checklrcfile(lrc, timespan) #print timespan return mylrcstr def getlrc(musicname): musicname=u''.join(musicname) musicname=musicname.encode('gb2312') for root,dirs,files in os.walk(lrcpath): for filepath in files: the_path = os.path.join(root,filepath) if (the_path.find(musicname) != -1): print the_path return the_path def errorlog(path): file=open(r'e:\nolrc.txt','a') if path is None: path='' path=path+'\n' file.write(path) file.close() def writetag(themusic,lrcstr): music=eyed3.load(themusic) lrcstr=lrcstr.decode('utf8') lrcstr=u''.join(lrcstr) #lrcstr=unicode(lrcstr) music.tag.lyrics.set(lrcstr) music.tag.save() def dealmusic(path): print path the_music = eyed3.load(path) the_teg = the_music.tag._getAlbum() the_artist = the_music.tag._getArtist() the_title = the_music.tag._getTitle() #print the_title try: lrc=getlrc(the_title) lrcstr=getlrcstr(lrc) writetag(path, lrcstr) except: errorlog(path) class writelrc(threading.Thread): def __init__(self,the_path): threading.Thread.__init__(self) self.thepath=the_path def run(self): dealmusic(self.thepath) if __name__=='__main__': count=0 threads=[] for root,dirs,files in os.walk(musicpath): for filepath in files: the_path = os.path.join(root,filepath) if (the_path.find("mp3") != -1): count+=1 threads.append(writelrc(the_path)) if count%10==0: for t in threads: t.start() for t in threads: t.join() threads=[]
好了，大概就是这样，大家有什么问题可以直接提出来，我会尽快回复的。
