How to Print List of Files in Directory and Subdirectories in Python

To print a list of files in a directory and its subdirectories in Python, you can use the “os.walk()” function. The os.walk() function generates file names in a directory tree by walking the tree either top-down or bottom-up.

Here’s a step-by-step guide on how to print a list of files in a directory and its subdirectories in Python:

Import the os module.
Define the starting directory.
Use the os.walk() function to iterate through the directory tree.
For each directory in the tree, print the file names.

Here’s an example.

import os

# Step 2: Define the starting directory
start_directory = "/Users/krunallathiya/Desktop/"

# Step 3: Use the os.walk() function to iterate through the directory tree
for root, dirs, files in os.walk(start_directory):
  # Step 4: Print the file names
  for file_name in files:
    # Combine the root directory path with the file name
    full_path = os.path.join(root, file_name)
    print(full_path)

Output

/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/index.js
/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/README.md
/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/package.json
/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/from.js
/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/file.js
/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/index.d.ts
/Users/krunallathiya/Desktop/Code/R/node_modules/fetch-blob/streams.cjs
/Users/krunallathiya/Desktop/Code/R/gol/hello.go

This script will print the full path of all files in the specified directory and its subdirectories.

That’s it.
