Python uses wxPython to open an audio file and play it back,

This example describes how python can open an audio file and play it back through wxPython. Share it with you for your reference. The details are as follows:

The code snippet uses the wx. lib. filebrowsebutton. FileBrowseButton control to open a wav file and play the file using wx. Sound.

import wximport wx.lib.filebrowsebuttonclass MyFrame(wx.Frame):  def __init__(self, parent, mytitle, mysize):    wx.Frame.__init__(self, parent, wx.ID_ANY, mytitle,      size=mysize)    self.SetBackgroundColour("green")    panel = wx.Panel(self)    # mask file browser to look for .wav sound files    self.fbb = wx.lib.filebrowsebutton.FileBrowseButton(panel,      labelText="Select a WAVE file:", fileMask="*.wav")    self.play_button = wx.Button(panel, wx.ID_ANY, ">> Play")    self.play_button.Bind(wx.EVT_BUTTON, self.onPlay)    # setup the layout with sizers    hsizer = wx.BoxSizer(wx.HORIZONTAL)    hsizer.Add(self.fbb, 1, wx.ALIGN_CENTER_VERTICAL)    hsizer.Add(self.play_button, 0, wx.ALIGN_CENTER_VERTICAL)    # create a border space    border = wx.BoxSizer(wx.VERTICAL)    border.Add(hsizer, 0, wx.EXPAND|wx.ALL, 10)    panel.SetSizer(border)  def onPlay(self, evt):    filename = self.fbb.GetValue()    self.sound = wx.Sound(filename)    # error handling ...    if self.sound.IsOk():      self.sound.Play(wx.SOUND_ASYNC)    else:      wx.MessageBox("Missing or invalid sound file", "Error")app = wx.App(0)# create a MyFrame instance and show the framemytitle = "wx.lib.filebrowsebutton and wx.Sound"width = 600height = 90MyFrame(None, mytitle, (width, height)).Show()app.MainLoop()
