Pathlib Tutorial: Transitioning to Simplified File and Directory Handling in Python

Introduction

Are you still using import os for file handling after 2020 ? Use pathlib instead !

If you're moving away from command line operations or 'os' module to Python's pathlib, you're at the right place.

Well, in this tutorial, we'll dive into the powerful pathlib module in Python. It offers a clean transition for users accustomed to CLI or 'os' for file and directory handling, providing an elegant and intuitive approach.

Removing Directories in Python

Remove Empty Directories in Python

To remove an empty directory, you can use os.rmdir() with os and Path.rmdir() with pathlib.

import os

directory_path = '/path/to/empty_directory'

try:
    os.rmdir(directory_path)
    print(f"The directory '{directory_path}' has been successfully removed.")
except OSError as e:
    print(f"Error: {directory_path} : {e.strerror}")

from pathlib import Path

directory_path = Path('/path/to/empty_directory')

try:
    directory_path.rmdir()
    print(f"The directory '{directory_path}' has been successfully removed.")
except OSError as e:
    print(f"Error: {directory_path} : {e.strerror}")
