How to Retrieve a Filtered List of Files in a Directory Using Python\'s `glob` Module?

Retrieving Filtered File Lists from a Directory in Python

Retrieving a comprehensive list of files within a directory is a common task in programming. However, it's often desirable to filter this list based on specific criteria. In Python, this can be achieved without resorting to external commands or the use of intricate for loops.

Python's glob module provides an efficient means of obtaining a filtered list of files. To illustrate its usage, consider the following scenario: you wish to extract a list of JPEG files containing the pattern "145592*".

To achieve this, utilize the following Python code:

import glob

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

In this example, glob.glob("145592.jpg") functions as a wildcard filter. It will identify all JPEG files within the specified directory that match the "145592" pattern. The resulting list, jpgFilenamesList, contains the filtered file paths.

The glob module offers additional flexibility by supporting various wildcard patterns. Consult the Python documentation for more details on these patterns and the full functionality of glob().

By employing the glob module, you can efficiently filter directories for specific files, saving time and effort compared to manually parsing through extensive file lists.
