前言
下面，我們開始介紹這個音樂播放器的制作過程。
一、核心功能設(shè)計
二、實現(xiàn)步驟
1. UI設(shè)計排版布局

爬取代碼寫好了，我們還需要將爬取的這些音樂數(shù)據(jù)列表顯示到畫面中搜索頁面中。代碼如下：
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('貌似沒網(wǎng)了呀`(*>﹏<*)′,再試一遍吧~')self.listwidget.item(0).setForeground(Qt.white)
