How to convert a .pptx to .pdf using Python?

Question

I have been looking to convert a .pptx file to a .pdf file through a Python script for several hours but nothing seems to be working. **What I have tried:** I have tried 1) [this script][1] which calls windows32.client, and 2) [unoconv][2], but none of them seem to be working for me. **Problems encountered:** Using script from first option throws up an error (`com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147024894), None)`), whereas in second option Python can't seem to recognize `unoconv` even after installing it using pip. I also saw some recommended [Pandoc][3], but I can't understand how to use it for Python. **Versions I am using:** Python 2.7.9, Windows 8.1 [1]: http://odetocode.com/blogs/scott/archive/2013/06/26/convert-a-directory-of-PowerPoint-slides-to-pdf-with-python.aspx [2]: http://dag.wiee.rs/home-made/unoconv/ [3]: http://pandoc.org/scripting.html

import comtypes.client

def PPTtoPDF(inputFileName, outputFileName, formatType = 32):

powerpoint = comtypes.client.CreateObject("Powerpoint.Application")

powerpoint.Visible = 1

if outputFileName[-3:] != 'pdf':

outputFileName = outputFileName + ".pdf"

deck = powerpoint.Presentations.Open(inputFileName)

deck.SaveAs(outputFileName, formatType) # formatType = 32 for ppt to pdf

deck.Close()

powerpoint.Quit()
