How to Filter Directory File Listings in Python using glob.glob()?

Filtering Directory File Listings in Python

In Python, obtaining a listing of all files in a directory is straightforward using the os.listdir() function. However, there are scenarios where it's desirable to filter this list based on specific criteria, such as file name patterns.

To filter a directory listing, Python offers the glob.glob() function. This function takes a file path pattern as its argument and returns a list of files matching that pattern within the specified directory.

For the example provided in the prompt, where it's desired to list all JPG files with names starting with "145592," the following Python code can be used:

<code class="python">import glob

jpgFilenamesList = glob.glob('145592*.jpg')</code>

The glob() function can handle complex file patterns, allowing advanced filtering based on file extensions, inclusion/exclusion criteria, and more. It's a convenient and versatile option for selectively listing files in a directory.

For further reference, detailed documentation on the glob module can be found in the Python documentation: https://docs.python.org/3/library/glob.html
