python - 谷歌实验室。 IPython.display - 音频在 if 语句中不起作用

Question

刚开始学习Python。我在 if 语句中遇到了音频的奇怪行为。它应该工作，但没有工作。

请参阅此处示例:https://colab.research.google.com/drive/1Jz6znaj047zrtDK-orp8VN0869xDYnQO?usp=sharing

此代码工作正常(播放 wav 文件):

from IPython.display import Audio

sound_hey = "http://thecyberbuddy.com/sounds/hooray.wav"

Audio(sound_hey, autoplay=True)  # plays ok

这不是:

from IPython.display import Audio

sound_boo = "http://mrclan.com/fastdl/tfc/sound/boo.wav"

s = 1

if s == 1:
  Audio(sound_boo, autoplay=True)  # dose not play...

Answer 1

这里

from IPython.display import Audio, display

sound_boo = "http://mrclan.com/fastdl/tfc/sound/boo.wav"

s = 1

if s == 1:
  display(Audio(sound_boo, autoplay=True))
