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 (se
