我无法通过 olefile 从 powerpoint 2003 文件中提取文本

Question

I can't extract text from Powerpoint 2003 ppt. After the following code, python shell will be 'not responding' or hang up.

import olefile
ole = olefile.OleFileIO('mypowerpoint.ppt')
text = ole.openstream('PowerPoint Document')
read = text.read()
print(read)

Answer 1

I think this is because the stream "PowerPoint Document" contains mostly binary data. So you would need to process it to extract the text before printing it.

Alternatively, you may use print(repr(read)) to see what it contains.
