I found the answer with the help of this post and the answer from this question.

Note that comtypes is only available for Windows. Other platforms will not support this.

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()
