I'm working with data processing and want to generate PowerPoint or OpenOffice Impress presentation with some data analysis directly from Python. Is there any libraries for Python to do that? I'm using Unix enviroment.
Yes.
You can use the odf
library.

The document you'll get will be in ODF format but you can later convert it to PPT using unoconv.
