Python/VLC：通过'；而'；环

我对编码和在动画展览中使用Python非常陌生。基本上，我正在编写代码来启动VLC播放器，从我的“剪辑”字典中播放一系列随机剪辑，并从我的“速度”字典中以随机速度播放每个剪辑

我遇到的问题是，一旦在第一个“while”循环中选择了一个速度，它就会以该速度播放接下来的每个片段。是否可以放置speed[speed_selection]元素，以便为每个剪辑选择重新选择速度

先谢谢你

*编辑：如果我删除“--one-instance”元素，VLC会在一个新的VLC窗口中打开每个剪辑，每个剪辑都有自己的速度（来自我的4种速度的字典）。因此，正是“-one instance”阻止了速度选择设置多个速度。我需要“--一个实例”让我的动画在一个屏幕上播放（当然），但这可能有助于我弄清楚如何在VLC的一个实例中编写代码来改变速度
