Pyqt4，选择本地路径，播放一段音频文件

使用python2.7,pyqt4,pygame模块，编写一个小程序。自定义寻找本地文件中的一个音频文件，并开始播放。

过程如下：

首先，通过文件对话框，选择一个音频文件的路径。

self.audioPath = QtGui.QFileDialog.getOpenFileName(self, C:\Users\Administrator\Desktop", all files(*.*)

然后，将文件路径转换为string类型 audioStr = str(self.audioPath)

最后，开始播放。 track = pygame.mixer.music.load(self.audioPath)pygame.mixer.music.play()
