Locating Files with glob in Python: A Step-By-Step Solution

If you're a Python programmer, you may encounter situations where you need to locate specific files in a directory. Whether you're gathering information, processing data, or simply organizing your work, you might find yourself stuck when trying to locate files. Recently, one reader struggled with their code while attempting to achieve this using the glob library. Today, we'll unravel this problem and provide you with an effective solution.

The Problem

Our reader presented code that was meant to find and print files from a specific folder but was encountering issues. Here’s the code they were using:

The intent was clear: locate a specified folder and print out its contents. However, the implementation contained several mistakes that made it ineffective.

Understanding the Issues

Several factors contributed to the problem in the reader's code:

Incorrect Use of f-string: The original code tried to format a string incorrectly.

Redundant Calls to glob.glob(): The reader called glob.glob() twice unnecessarily.

Handling of the Results: The use of os.path.basename() was applied to the entire list instead of the individual file paths.

The Solution

Now that we understand the issues at hand, let’s break down the solution into clear, manageable steps.

1. Correctly Use f-Strings

To format the pathname properly, an f-string should be utilized to directly embed the variable within the string.

2. Use ** for Recursive Search

To search through all folders, use ** in your globbing pattern and set recursive=True.

3. Loop Through Results

Instead of trying to get a basename from a list, loop through each file returned by glob.glob() and call os.path.basename() on each file path.

Here’s the corrected code:

How It Works

Input Prompt: The code first prompts the user for a folder name.

File Search: Using glob.glob(), it searches for all files in the specified folder and any subfolders.

Display Results: A for loop iterates over the found files, and os.path.basename() extracts non-directory names to print them cleanly.

Conclusion

In this guide, we've addressed the common pitfalls in using the glob library in Python for file searching and provided a straightforward solution. By correcting the use of f-strings, applying recursive search properly, and handling results correctly, you can efficiently locate and print files from directories.

Now it's your turn! Try implementing this solution in your projects, and enjoy the ease of locating files in Python with glob.
