The OS module in Python provides functions for creating and removing a directory (folder), fetching its contents, changing and identifying the current directory, etc.

Get Current Working Directory

import os

os.getcwd()

Creating a Directory

import os

os.getcwd()
os.mkdir("MyPythonProject")

Changing the Current Working Directory

import os

os.chdir("C:\MyPythonProject") # changing current workign directory
os.getcwd()

Change CWD to Parent

import os

os.chdir("..")
os.getcwd()

Removing a Directory
We change the current working directory to the parent directory using os.chdir("..") and then remove it using the rmdir() function.

import os

os.chdir("..")
os.rmdir("MyPythonProject")

List Files and Sub-directories
The listdir() function returns the list of all files and directories in the specified directory.

import os

os.listdir()
os.listdir("c:\python37")

#End
