How can I effectively distinguish between files and directories when using Python's os.walk() function?

Leveraging Python's os.walk() for Recursive Directory Exploration

In Python, traversing directories recursively is a crucial task for tasks like file management and directory manipulation. The versatile os.walk() function provides a robust solution for this purpose.

When navigating directories, it's often essential to distinguish between files and directories. However, the os.walk() function presents data differently. To address this, leveraging additional tools becomes necessary.

To exemplify this, consider the following code snippet:

import os
import fnmatch

for root, dir, files in os.walk("."):
    print(root)
    print("")
    for items in fnmatch.filter(files, "*"):
        print("..." + items)
    print("")

When executed, this code prints the structure of the current directory, followed by files within each directory. However, this structure doesn't align with the desired format, where files and directories are clearly distinguished.

To achieve the desired output, an alternative approach using a slightly modified os.walk() implementation is necessary:

import os

for root, dirs, files in os.walk("."):
    path = root.split(os.sep)
    print((len(path) - 1) * '---', os.path.basename(root))
    for file in files:
        print(len(path) * '---', file)

This revised code divides the root directory path into individual components (path) and counts the number of components to determine the depth of the current directory. This depth is then used to indent the directory name and files within it for proper visualization. The final output, therefore, reflects a hierarchical representation with directories and files clearly segregated.
