Python - 如何在不设置计时器的情况下等待函数完成进程

如何解决Python - 如何在不设置计时器的情况下等待函数完成进程

这是我第一次使用 python，我不了解过程：

我正在使用 Pocketsphinx 进行语音到文本的转换，但函数 createAudio(videoclip): 有问题。该脚本不会运行整个 transcript() 函数，或者只运行几秒钟直到下一个函数启动。我怎样才能让 transcript() 函数运行直到它完成并且下一个可以开始/跟随，而无需设置计时器？因为后面的视频文件会越来越大，大小不一。

用于测试：.wav 文件有 300MB 大，文本输出只有 4 个字

def createAudio(videoclip):

pathOfSameFolder=str(pathOfFolder)
dirCreated = True

try:
    newDir=createDirectory(pathOfSameFolder)
except OSError:

    print ('Error: Creating directory. ' +  str(pathOfSameFolder) + ' may be existing!')
    dirCreated = False 

if dirCreated :
    audioclip = videoclip.audio
    audioclip.write_audiofile(mp3_file)
    audioclip.close()
    videoclip.close()
    print('Converting audio transcripts into text ...')
    transcript()
    directoryMove(newDir)

这是完整的代码：

解决方法

Python 是（除非指定）一种同步语言，这意味着在前一个进程未完成时，进程不会/无法启动。

适用于您的情况，如果您的 directoryMove() 函数被执行，则意味着您的 transcript() 函数以一种或另一种方式完全完成（可能失败了）。

您可以在这两个函数中打印更多调试日志，以说服自己并帮助您进一步调查问题所在。

了解转录的功能会很有用吗？我想它正在启动一个线程。在这种情况下，您必须捕获一个线程 id 并 join() 它以等待线程结束
