对了，一个背景故事。对于我的大学项目，我正在为鼓创建一个节奏老师。所以程序要做的是加载一个鼓谱，以及一个与该鼓谱匹配的音频文件。用户按下“播放”按钮，它会播放一段与乐谱相匹配的短鼓。到目前为止，我有一个按钮可以播放加载的 Wav。文件，以及另一个加载图像的按钮。我希望我说得通。

所以我的问题是，有没有人可以做到这一点？如，一个按钮，将图像和音频文件一起加载。如果再次按下按钮，它将加载另一个图像和音频文件，覆盖之前加载的任何内容。我将加载大量图像和音频文件。重要的是图像必须与音频文件匹配。

同样，我有一个播放音频文件的按钮，另一个只是加载图像的按钮（我这样做是因为我是新手，并且正在学习如何执行这些功能。

无论如何我都会发布一个代码，它应该更有意义！对不起，如果它是一个长期阅读！只是想我会在我正在做的事情上写一个背景故事。

这是您可以做到的一种方法：

  • 首先，定义全局变量，定义包含图像和 wav 文件的目录：

    IMAGE_DIR = '/path/to/images'
SOUND_DIR = '/path/to/sounds'

    如果您愿意，可以使用相同的目录。我会假设

    • .jpg所有图像都是以,结尾的 JPEG 文件
    • 如果调用图像，则调用foo.jpg关联的 wav 文件foo.wav。

  • 接下来，在window2.__init__方法中定义两个新属性：

    self.images = IT.cycle([filename for filename in os.listdir(IMAGE_DIR) if filename.endswith('.jpg')])
self.image_file = None

    并在文件顶部导入itertools模块：

    import itertools as IT

    os.listdir(IMAGE_DIR)返回文件名列表。IT.cycle 返回一个循环遍历列表中的项目的可迭代对象。

    next(self.images) 一次返回可迭代项中的项 self.images——每次调用 next. 我们将在下面使用它。

  • 现在，loadImage可能会这样写：

    def loadImage(self, event):
    self.image_file = next(self.images)
    image_file = os.path.join(IMAGE_DIR, self.image_file)
    bmp = wx.Image(image_file, wx.BITMAP_TYPE_ANY).ConvertToBitmap()
    wx.StaticBitmap(self.panel, -1, bmp, pos=(200, 50), size=(417, 133))

并播放相关的 wav 文件：

   def onPlaySound(self, event):  
        sound_file, ext = os.path.splitext(self.image_file)
        sound_file = os.path.join(SOUND_DIR, sound_file + '.wav')
        sound = wx.Sound(sound_file)
        sound.Play(wx.SOUND_ASYNC)

由于正在使用os.path.join和os.path.splitext，因此请务必os在文件顶部也导入模块。
