How to solve powerpoint break issue while converting pdf to ppt python

If you are facing below issue while converting pdf to ppt in python

Traceback (most recent call last):
ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1)
com_error: (-2147417848, 'The object invoked has disconnected from its clients.', None, None)

There is below fix for this issue.
Earlier code was calling convert method and passing files to method

convert(files,pathout)
def convert(files, outputdir,formatType = 32):
    powerpoint = win32com.client.Dispatch("Powerpoint.Application")
    powerpoint.Visible = 1
    for filename in files:
       # convert(filename,pathout)
        print(filename)
        print(outputdir)
        newname = os.path.splitext(filename)[0] + ".pdf"
        newname = os.path.split(newname)[1]
        print(newname)
        newname = os.path.join(outputdir,newname)
        deck = powerpoint.Presentations.Open(filename)
        deck.SaveAs(newname, formatType)
        deck.Close()
        powerpoint.Quit()

For fix what needs to be done is  call convert method with one file i.e. have outer for loop which will iterate files and pass one file to convert method like below.

 for filename in files:
       convert(filename,pathout)

def convert(filename, outputdir,formatType = 32):
    powerpoint = win32com.client.Dispatch("Powerpoint.Application")
    powerpoint.Visible = 1
    #for filename in files:
       # convert(filename,pathout)
        print(filename)
        print(outputdir)
        newname = os.path.splitext(filename)[0] + ".pdf"
        newname = os.path.split(newname)[1]
        print(newname)
        newname = os.path.join(outputdir,newname)
        deck = powerpoint.Presentations.Open(filename)
        deck.SaveAs(newname, formatType)
        deck.Close()
        powerpoint.Quit()

For me  issue was resolved with this change.
