喜爱的歌初始化读取：
重新运行音乐播放器时，我们需要加载保存在本地的喜爱歌曲数据，并将歌曲列表信息加载显示到喜爱的歌子列表页面中 。核心代码如下：
def run(self):try:apdataas = getenv("APPDATA")filepathas = '{}/musicdata'.format(apdataas)global lovelrcglobal loveurlsglobal lovesglobal lovepicsglobal voice# 读取历史数据开始try:with open(filepathas + "/voice", 'r', encoding='utf-8') as f:a = f.read()# print(a)voice = float(a)print(voice)self.trigger.emit(str('voicedone'))except:self.trigger.emit(str('voicedone'))passwith open(filepathas + "/loves", 'r', encoding='utf-8') as f:a = f.read()print(a)strer = aloves = literal_eval(strer)with open(filepathas + "/lovepics", 'r', encoding='utf-8') as f:a = f.read()print(a)strer = alovepics = literal_eval(strer)with open(filepathas + "/loveurls", 'r', encoding='utf-8') as f:a = f.read()print(a)strer = aloveurls = literal_eval(strer)with open(filepathas + "/lovelrc", 'r', encoding='utf-8') as f:a = f.read()print(a)strer = alovelrc = literal_eval(strer)self.trigger.emit(str('login'))print(loves)print('read finish')except:print('read error')pass# 读取数据结束# 下载喜爱的歌列表中首项的歌曲封面try:req = get(lovepics[0])checkfile = open(str(data + '/ls3.png'), 'w+b')for i in req.iter_content(100000):checkfile.write(i)checkfile.close()lsfile = str(data + '/ls3.png')safile = str(data + '/first.png')draw(lsfile, safile)self.trigger.emit(str('first'))except:self.trigger.emit(str('nofirst'))pass列表播放：
对于加载的喜爱歌曲列表，我们可以对歌曲进行列表一键播放 。
