How to Efficiently Filter File Listings in Python using the glob Module?

Filter File Listing in Python

The task of retrieving a filtered list of files within a directory using Python is common. This discussion examines methods to efficiently achieve this without relying on external commands like "ls".

Efficient Solution Using glob

Python offers a built-in module called glob, which simplifies the process of searching for files with specific patterns. By leveraging its glob() function, you can effectively filter the list of files in a directory:

import glob

jpgFilenamesList = glob.glob('145592*.jpg')

This snippet identifies all files with names matching the "145592*.jpg" pattern within the current directory and stores them in a list named jpgFilenamesList. The glob() function automatically applies the specified pattern to the list of files in the directory.

Detailed Explanation:

The glob() function takes a pattern as an argument and searches for files or directories that match that pattern. It then returns a list of matching paths. In this case, the pattern "145592*.jpg" represents filenames starting with "145592" and ending with ".jpg".
