Q:

import os python

The OS module in Python provides a way of using operating system dependent
functionality. 

The functions that the OS module provides allows you to interface with the
underlying operating system that Python is running on – be that Windows, Mac or
Linux. 

You can find important information about your location or about the process. 

In this post I will show some of these functions.

Set the current numeric umask and return the previous umask.
os.umask(mask)
