It can also save the output diagram to a file in markdown format. It’ll take arguments, process them, and display a directory tree diagram on the terminal window. Your directory tree generator tool will run on the command line.

cli.py provides the command-line interface for the application.

_init_.py enables rptree/ as a Python package.

rptree.py provides the application’s main functionalities.

Then you have the rptree/ directory that holds a Python package with three modules: Tree.py provides an entry-point script for you to run the application. Adding a descriptive and detailed README file to your projects is considered a best practice in programming, especially if you’re planning to release the project as an open source solution. README.md provides the project description and instructions on installing and running the application. The rptree_project/ directory is the project’s root directory. Your directory tree generator will provide a fully functional but minimal CLI with a couple of options that allow you to generate and display a tree diagram listing all the files and directories in a given root directory.

Here’s how the application will look and work once you get to the end of this tutorial: It’ll also provide some interesting features, such as displaying a tree diagram with the contents of a directory on your terminal window and saving the diagram to an external file. Your directory tree generator will have a user-friendly CLI. You’ll also find this diagram referred to as a directory tree diagram throughout the tutorial. The tool you’ll build here will allow you to generate and display a treelike diagram listing the internal structure of a given directory in your file system.

This tutorial refers to the kind of tool described above as a directory tree generator. However, figuring out your own solution to this problem would be a good learning exercise. You’ll find tools like the tree command, which is available on most operating systems, plus other tools, like treelib, dirtriex, and so on. There are already several mature solutions out there that perform this task. In this tutorial, you’ll build a command-line tool to list the contents of a directory or folder in a treelike diagram.
