AttributeError

When I run your code, I meet an error:

Traceback (most recent call last):
  File "convert.py", line 24, in <module>
    powerpoint = init_powerpoint()
  File "convert.py", line 5, in init_powerpoint
    powerpoint = comtypes.client.CreateObject("Powerpoint.Application")
  File "D:\software\Anaconda\envs\MCM\lib\site-packages\comtypes\client\__init__.py", line 250, in CreateObject
    return _manage(obj, clsid, interface=interface)
  File "D:\software\Anaconda\envs\MCM\lib\site-packages\comtypes\client\__init__.py", line 188, in _manage
    obj = GetBestInterface(obj)
  File "D:\software\Anaconda\envs\MCM\lib\site-packages\comtypes\client\__init__.py", line 112, in GetBestInterface
    interface = getattr(mod, itf_name)
AttributeError: module 'comtypes.gen.PowerPoint' has no attribute '_Application'

The solution to this problem is change the method init_powerpoint to:

def init_powerpoint():
    powerpoint = win32com.client.DispatchEx("Powerpoint.Application")
    return powerpoint

Probably will not work if the PowerPoints are not in the current working directory?

Shouldn't the second last line in the below be

fullpath = os.path.join(folder, pptfile)

not cwd?

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(cwd, pptfile)
        ppt_to_pdf(powerpoint, fullpath, fullpath)

suggestion

provide the required library of the script. Like: "lock" file
the resulted file end with ".pdf", not ".pptx.pdf" or ".pptx.pdf"

that is all, thank you :)

'Powerpoint.Application' is invalid class string

Python version: 3.6.5 ，the error message '无效的类字符串' means 'invalid class string', my pc does not install Microsoft office.I use LibreOffice, does this reason cause the error?
