In this Python tutorial, you’ll create a Python directory tree generator application for your command line. You’ll code the command-line interface with argparse and traverse the file system using pathlib.

Creating applications with a user-friendly command-line interface (CLI) is a useful skill for a Python developer. With this skill, you can create tools to automate and speed up tasks in your working environment. In this tutorial, you’ll build a Python directory tree generator tool for your command line.

The application will take a directory path as an argument at the command line and display a directory tree diagram on your screen. It’ll also provide other options to tweak the output.

In this tutorial, you’ll learn how to:

• Create a CLI application with Python’s argparse
• Recursively traverse a directory structure using pathlib
• Generate, format, and display a directory tree diagram
• Save the directory tree diagram to an output file
