前言
下面，我们开始介绍这个音乐播放器的制作过程。
一、核心功能设计
二、实现步骤
1. UI设计排版布局

爬取代码写好了，我们还需要将爬取的这些音乐数据列表显示到画面中搜索页面中。代码如下：
def repite(self, name, type):global tryedglobal paingglobal stopself.listwidget.clear()self.listwidget.addItem('搜索中')self.listwidget.item(0).setForeground(Qt.white)try:if paing:stop = Trueself.listwidget.clear()self.work2 = PAThread()self.work2.start()self.work2.trigger.connect(self.seafinish)else:self.work2 = PAThread()self.work2.start()self.work2.trigger.connect(self.seafinish)except:tryed = tryed + 1get_info('https://www.kuaidaili.com/free/inha')self.listwidget.addItem('貌似没网了呀`(*>﹏<*)′,再试一遍吧~')self.listwidget.item(0).setForeground(Qt.white)

（3）单曲循环：
def always(self):try:if bo == 'boing':self.label.setText(songs[num])else:self.label.setText(songed[num])self.bofang(num, bo) # 播放音乐except:pass
（4） 播放模式选择：

音量提高/降低：
