我不知道为什么,但它只发现,转换和转录目录中的所有mp3文件偶尔,但从来没有百分之百的时间。我不知道为什么。我希望我问得对。我的目标是找到所有m4a文件,然后转换成wav文件,然后找到所有wav文件并转录它们。程序有时会这样做,但不是所有的时间

# find all files with an extension, convert to wav files, transcribe to text file then transfer all wav files and mp3 files to finished directory and email transcribed files.
# find files with mp3 extension
def list_files1(directory, extension):
ext = []

ext.append(file)

电子dit:It was 我犯了一个非常愚蠢的错误,我把所有输出的文本文件命名为同一个名称,这样它们就会被覆盖。我确保给它们一个唯一的名称,把名称降到毫秒,然后在文件名中添加一个随机数
当您使用
os.walk()
时,它返回没有任何目录的文件,因此您正在收集一个文件列表,但丢弃了它们的目录名包装器似乎没有在
os.walk()
上添加任何值;无论如何,我都会重构一次转换一个文件。另外,如果不特别关心当前目录的绝对路径,也不需要调用getcwd
