How to Extract Folder Names and File Names with Digits in Python

If you've ever faced the challenge of extracting folder names and file names that contain digits within a specific file path in Python, you're not alone. This is a common task, especially for those managing large projects with multiple directories and files. In this guide, we will explore how to achieve this using Python's pathlib library. Let's dive right in!

Understanding the Problem

You might have directories structured in a way where they include names that are purely numeric, and you want to identify these names. Additionally, you want to check if any files within those directories contain digits in their names as well. If no digits are found in the folder names, the task is to retrieve the file names instead.

Example Directory Structure

Here's an example of how your folders might be organized:

Solution: Using Pathlib to Extract Folder and File Names

Python's pathlib library offers a more intuitive and readable way to navigate filesystem paths compared to the older os module. Here's a step-by-step guide to extracting the desired names.

Step 1: Set Up Your Base Project Folder

First, you'll need to specify the base folder from which you want to start searching for files and folders.

Step 2: Use Pathlib to Gather Files

Next, we will create a list comprehension to gather all files that include digits in their names. This list comprehension will also ensure that only files (not folders) are included.

Step 3: Print Out Results

Finally, you can loop through the filtered list of files and print out their respective project folder name and filename.

Conclusion

In this guide, we covered how to extract folder names and file names containing digits from a specified path in Python using the pathlib library. By utilizing the powerful features of pathlib, we can write clearer and more maintainable code compared to traditional methods.
