如何在 python 中使用带有 playsound 的循环？

Question

我正在制作一个莫尔斯电码程序，所以我需要使用带有 playsound 模块的循环来一次又一次地播放短而长的哔哔声。 这些文件在没有循环的情况下正常播放，但是当我添加一个循环时，我遇到了错误。

from playsound import playsound
import time

for i in range(0, 5):
    playsound('long.mp3')
    time.sleep(0.5)
    playsound('short.mp3')
    time.sleep(0.5)

 Error 263 for command: open long.mp3 The specified device is not open or is not recognized by MCI. Error 263 for command: close long.mp3 The specified device is not open or is not recognized by MCI. Failed to close the file: long.mp3 Traceback (most recent call last): File "C:\Users\achin\PycharmProjects\Morse code\ok.py", line 5, in <module> playsound('long.mp3') File "C:\Users\achin\PycharmProjects\Morse code\venv\lib\site-packages\playsound.py", line 72, in _playsoundWin winCommand(u'open {}'.format(sound)) File "C:\Users\achin\PycharmProjects\Morse code\venv\lib\site-packages\playsound.py", line 64, in winCommand raise PlaysoundException(exceptionMessage) playsound.PlaysoundException: Error 263 for command: open long.mp3 The specified device is not open or is not recognized by MCI.

Answer 1

您是否尝试过使用 with 语句？ 它看起来像这样：

from playsound import playsound
import time

with open('long.mp3') as long_beep, open('short.mp3') as short_beep:
  for i in range(0, 5):
    playsound(long_beep)
    time.sleep(0.5)
    playsound(short_beep)
    time.sleep(0.5)

另外，它似乎可能是 playsound 的错误（？），尝试降级到 playsound 1.2.2 （ pip install playsound==1.2.2 ）并再次尝试您的代码
