Python实现批量将ppt转换为pdf

import comtypes.client
import os
def init_powerpoint():
 powerpoint = comtypes.client.CreateObject("Powerpoint.Application")
 powerpoint.Visible = 1
 return powerpoint
def ppt_to_pdf(powerpoint, inputFileName, outputFileName, formatType = 32):
 if outputFileName[-3:] != 'pdf':
  outputFileName = outputFileName + ".pdf"
 deck = powerpoint.Presentations.Open(inputFileName)
 deck.SaveAs(outputFileName, formatType) # formatType = 32 for ppt to pdf
 deck.Close()
def convert_files_in_folder(powerpoint, folder):
 files = os.listdir(folder)
 pptfiles = [f for f in files if f.endswith((".ppt", ".pptx"))]
 for pptfile in pptfiles:
  fullpath = os.path.join(folder, pptfile)
  ppt_to_pdf(powerpoint, fullpath, fullpath)
if __name__ == "__main__":
 powerpoint = init_powerpoint()
 cwd = os.getcwd()
 convert_files_in_folder(powerpoint, cwd)
 powerpoint.Quit()
