    pres.save(pdf_file_path, slides.export.SaveFormat.PDF)

3. python-magic: python-magic is a Python interface to the libmagic file type identification library. libmagic identifies file types by checking their headers according to a predefined list of file types. This functionality is exposed to the command line by the Unix command file.

Installation: pip install python-magic

Documentation: https://magic.readthedocs.io/_/downloads/en/stable/pdf/

import magic

def is_pdf(file_path):
    mime = magic.Magic(mime=True) # Initialize instance of Magic with type
    file_mime_type = mime.from_file(file_path) # Load the file 
    return file_mime_type == 'application/pdf' # return tru of file is pdf.

def is_ppt(file_path):
    mime = magic.Magic(mime=True)
    file_mime_type = mime.from_file(file_path)
    return file_mime_type == 'application/vnd.ms-powerpoint'

def is_docx(file_path):
    mime = magic.Magic(mime=True)
    file_mime_type = mime.from_file(file_path)
    return file_mime_type == "application/vnd.openxmlformats-officedocument.wordprocessingml.document" or file_mime_type == "application/msword"

• file_mime_type == "application/vnd.openxmlformats-officedocument.wordprocessingml.document" for .docx
• file_mime_type == "application/msword" for .doc
• file_mime_type == 'application/vnd.ms-powerpoint' for .ppt
• file_mime_type == 'application/pdf' for .pdf

Things that I have encounter creating this projects:

1. Conversion of PPT to PDF: I have really hard time on conversion of PPT to PDF. I want a python module that can convert PPT to PDF without any windows or ubuntu OS. But I have found a package name aspose.slide. pip install Aspose.Slide. This package don't use any ms powerpoind or anything. Besides I have came to know its module is written on cpython which is in format slides.cpython-37m-x86_64-linux-gnu.so which needs libpython<version>.so.1.o. So better note it if you face any problems installing this application. And another ubuntu dependency libgdiplus which can be installed by command sudo apt-get install -y libgdiplus.
