Convert MS Word files into PDF format using Python on Windows

"""
The following code converts "doc" and "docx" files to "pdf". But once it opens the files, due to some issue in our code
(usually an unattended Word prompt) it does not closes the files properly and the Operating System file lock 
remains open on the file. So the code runs for one time but not the second time unless we end the "Word" program 
instances from the Task Manager.
