import os
os.chdir('C:\\Users\\Mithun\\Documents')
ii) os.rmdir(path)
Purpose: Removes an empty directory.
os.rmdir('old_folder')
iii) os.walk(path)
Purpose: Walks through a directory tree (i.e., all folders and files inside a directory).
for foldername, subfolders, filenames in os.walk('.'):
print('Folder:', foldername)
print('Files:', filenames)
iv) os.listdir(path)
Purpose: Lists all files and directories in the given path.
print(os.listdir('.'))
