python os module commit

[premkumargrk]

Describe your change

This PR uploads a new folder containing examples and utilities built with Python’s os module.
The code demonstrates how Python can interact with and respond to our operating system by performing tasks such as:

• Directory operations (create, rename, remove, navigate)
• Path handling (absolute paths, basename, dirname, join, existence checks)
• Environment variable management (get, set, unset)
• Running system commands (ls/dir)
• Process information (PID, CPU count)
• File access and permissions (read/write checks, file size)
• Cleanup operations

Purpose

The folder serves as a practical reference for developers and learners to understand how Python communicates with the OS, making it easier to manage files, directories, and system-level tasks programmatically.

Checklist

• Code follows Python naming conventions
• Added doctests/examples for reproducibility
• Single algorithm file/folder added
• Documentation included in comments
