前言
本文給大家分享的是如何通過利用Python實現多功能音樂播放器,廢話不多直接開整~
開發工具
Python版本: 3.6
相關模組:
os模組
sys模組
time模組
random模組
PyQt5模組
環境搭建
安裝Python並新增到環境變數,pip安裝需要的相關模組即可。
文中完整原始碼,評論留言獲取。

根據播放模式播放音樂
def playByMode(self): if (not self.is_pause) and (not self.is_switching): self.slider.setMinimum(0) self.slider.setMaximum(self.player.duration()) self.slider.setValue(self.slider.value() + 1000) self.label1.setText(time.strftime('%M:%S', time.localtime(self.player.position()/1000))) self.label2.setText(time.strftime('%M:%S', time.localtime(self.player.duration()/1000))) # 順序播放 if (self.cmb.currentIndex() == 0) and (not self.is_pause) and (not self.is_switching): if self.qlist.count() == 0: return if self.player.position() == self.player.duration(): self.nextMusic() # 單曲迴圈 elif (self.cmb.currentIndex() == 1) and (not self.is_pause) and (not self.is_switching): if self.qlist.count() == 0: return if self.player.position() == self.player.duration(): self.is_switching = True self.setCurPlaying() self.slider.setValue(0) self.playMusic() self.is_switching = False # 隨機播放 elif (self.cmb.currentIndex() == 2) and (not self.is_pause) and (not self.is_switching): if self.qlist.count() == 0: return if self.player.position() == self.player.duration(): self.is_switching = True self.qlist.setCurrentRow(random.randint(0, self.qlist.count()-1)) self.setCurPlaying() self.slider.setValue(0) self.playMusic() self.is_switching = False
程式碼有點多~~
