Introduction

In this tutorial, we’ll explore a Python programming problem that involves writing a program to list all files ending with .txt in the current directory as well as sub-directories, recursively.

By the end of this post, you’ll have a better understanding of how to work with directories, search for files, and create efficient algorithms for recursively listing files.

Step 1: Importing the Required Modules

First, let’s import the required modules for working with directories and files in Python:

import os

Step 2: Defining the Function

Next, let’s define a function called list_txt_files that takes a single argument, directory, which is the directory to search for .txt files:

def list_txt_files(directory):
    # Recursively list all .txt files in the directory

Step 3: Initializing the List
