音乐脚本代码（【脚本项目源码】Python制作多功能音乐播放器，打造专属你的音乐播放器）

前言

本文给大家分享的是如何通过利用Python实现多功能音乐播放器
  
  
  
  
  
  
 ，废话不多直接开整~

开发工具

Python版本： 3.6

相关模块：

os模块

sys模块

time模块

random模块

PyQt5模块

环境搭建

安装Python并添加到环境变量 
  
  
  
  
  
  ，pip安装需要的相关模块即可

代码实现

初始化

def __initialize(self): self.setWindowTitle(音乐播放器-Python工程狮) self.setWindowIcon(QIcon(icon.ico)) self.songs_list = [] self.song_formats = [mp3, m4a, flac, wav, ogg] self.settingfilename = setting.ini self.player = QMediaPlayer() self.cur_path = os.path.abspath(os.path.dirname(__file__)) self.cur_playing_song = self.is_switching = False self.is_pause = True # 界面元素 # --播放时间 self.label1 = QLabel(00:00) self.label1.setStyle(QStyleFactory.create(Fusion)) self.label2 = QLabel(00:00) self.label2.setStyle(QStyleFactory.create(Fusion)) # --滑动条 self.slider = QSlider(Qt.Horizontal, self) self.slider.sliderMoved[int].connect(lambda: self.player.setPosition(self.slider.value())) self.slider.setStyle(QStyleFactory.create(Fusion)) # --播放按钮 self.play_button = QPushButton(播放, self) self.play_button.clicked.connect(self.playMusic) self.play_button.setStyle(QStyleFactory.create(Fusion)) # --上一首按钮 self.preview_button = QPushButton(上一首, self) self.preview_button.clicked.connect(self.previewMusic) self.preview_button.setStyle(QStyleFactory.create(Fusion)) # --下一首按钮 self.next_button = QPushButton(下一首, self) self.next_button.clicked.connect(self.nextMusic) self.next_button.setStyle(QStyleFactory.create(Fusion)) # --打开文件夹按钮 self.open_button = QPushButton(打开文件夹, self) self.open_button.setStyle(QStyleFactory.create(Fusion)) self.open_button.clicked.connect(self.openDir) # --显示音乐列表 self.qlist = QListWidget() self.qlist.itemDoubleClicked.connect(self.doubleClicked) self.qlist.setStyle(QStyleFactory.create(windows)) # --如果有初始化setting, 导入setting self.loadSetting() # --播放模式 self.cmb = QComboBox() self.cmb.setStyle(QStyleFactory.create(Fusion)) self.cmb.addItem(顺序播放) self.cmb.addItem(单曲循环) self.cmb.addItem(随机播放) # --计时器 self.timer = QTimer(self) self.timer.start(1000) self.timer.timeout.connect(self.playByMode) # 界面布局 self.grid = QGridLayout() self.setLayout(self.grid) self.grid.addWidget(self.qlist, 0, 0, 5, 10) self.grid.addWidget(self.label1, 0, 11, 1, 1) self.grid.addWidget(self.slider, 0, 12, 1, 1) self.grid.addWidget(self.label2, 0, 13, 1, 1) self.grid.addWidget(self.play_button, 0, 14, 1, 1) self.grid.addWidget(self.next_button, 1, 11, 1, 2) self.grid.addWidget(self.preview_button, 2, 11, 1, 2) self.grid.addWidget(self.cmb, 3, 11, 1, 2) self.grid.addWidget(self.open_button, 4, 11, 1, 2)

根据播放模式播放音乐

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))) # 顺序播放 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() # 单曲循环 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 # 随机播放 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

代码有点多~~
