Python

shutil & os module:

• Open file
• Edit file
• Listing all files from folder.
• Listing all files from nested child folders.
• delete file / folder
• rename file / move folder

Important methods from os module:

methods	description
os.getcwd()	get current working directory
os.listdir()	list all files and folder from current working directory
os.listdir(dir_path)	list all files and folder from given directory path
os.walk()	iterate all files and nested child directories from current working directory. This return tuple object (folder, sub_folders, files)
os.walk(dir_path)	iterate all files and nested child directories from given directory. This return tuple object (folder, sub_folders, files)
os.unlink(path)	delete file / folder

Important methods from shutil module:

methods	description
shutil.copy(src_path, dest_path)	copy file from source path to destination path
shutil.copy2(src_path, dest_path)	copy file from source path to destination path along with all attribute from source file. Example, - executable permission, last change date, create by, created on, etc.
shutil.move(src_path, dest_path)	move file from source path to destination path
shtuil.delete(path)	delete file / folder
shutil.rmtree(path)	delete file / folder. This operation will delete file / folder permenant from file system (Not use Recycle Bin). Most of developer not recommending this operation.

Example for os.walk method:

import os;
for folder, sub_folders, files in os.walk('D:\Workspaces\python-workspace\simple-code'):
	print(f'Folder {folder}')
	for sub_folder in sub_folders:
		print(f'\t\t Sub Folder - {sub_folder}')
	for file in files:
		print(f'\t\t File - {file}')

Output:

Folder D:\Workspaces\python-workspace\simple-code
		 Sub Folder - .ipynb_checkpoints
		 File - Collections.ipynb
		 File - decorators.ipynb
		 File - generators.ipynb
		 File - Untitled.ipynb
Folder D:\Workspaces\python-workspace\simple-code\.ipynb_checkpoints
		 File - Collections-checkpoint.ipynb
		 File - decorators-checkpoint.ipynb
		 File - generators-checkpoint.ipynb
		 File - Untitled-checkpoint.ipynb
