Use fnmatch.filter to filter files by more than one possible file extension in python

Use fnmatch.filter to filter files by more than one possible file extension in python

You can use the fnmatch.filter() function to filter files by more than one possible file extension in Python by providing a list of patterns to match against. Here's how you can do it:

import fnmatch
import os

# Directory where you want to filter files
directory = "/path/to/your/directory"

# List of possible file extensions to filter
extensions = ['*.txt', '*.csv', '*.json']

# Use a list comprehension to filter files with any of the specified extensions
filtered_files = [filename for filename in os.listdir(directory) if any(fnmatch.fnmatch(filename, pattern) for pattern in extensions)]

# Print the filtered files
for filename in filtered_files:
    print(filename)

In this code:

  1. Specify the directory where you want to filter files by setting the directory variable to the appropriate path.

  2. Create a list of possible file extensions you want to filter by, such as ['*.txt', '*.csv', '*.json'].

  3. Use a list comprehension to filter files by iterating over the contents of the specified directory. For each filename, the fnmatch.fnmatch() function checks if it matches any of the specified patterns in the extensions list using any(). If a match is found, the filename is included in the filtered_files list.

  4. Finally, you can print or process the filtered files as needed.

This code will filter files in the specified directory by any of the specified file extensions, allowing you to select files with multiple possible extensions.
