Python Glob regex file search with for single result from multiple matches

The glob module in Python is a powerful tool for file searching, but it doesn't natively support regular expressions. However, you can easily combine glob with the re (regular expression) module to search for files that match a specific regular expression pattern and retrieve a single result from multiple matches. In this tutorial, we will walk you through the process with code examples.
Before we get started, make sure you have Python installed on your system. You will also need to import the glob and re modules.
To use glob and re, you need to import them in your Python script.
Create a regular expression pattern that matches the files you're looking for. For example, if you want to find all files with a .txt extension, you can use the following pattern:
If you want a single result from multiple matches, you can filter the results as needed. For example, to retrieve the first matching file, you can simply access the first element of the file_matches list:
Here's a complete example that searches for all .txt files in a directory and retrieves the first match:
You can modify the regular expression pattern to match your specific file naming conventions or extensions. The above example can be adapted to search for various types of files based on your needs.
Combining Python's glob and re modules allows you to perform flexible and powerful file searches using regular expressions. You can easily customize this approach to find and retrieve the files that meet your criteria within a directory.
