谷歌Colab。IPython.display音频在if语句中不工作

Question

刚开始学习Python。我在{}语句中遇到了一种奇怪的音频行为。它应该会起作用，但不起作用

请参见此处的示例：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))
