# Python script to sort files in a directory by their extension
import os
from shutil import move
def sort_files(directory_path):
for filename in os.listdir(directory_path):
if os.path.isfile(os.path.join(directory_path, filename)):

destination_directory = os.path.join(directory_path, file_extension)
if not os.path.exists(destination_directory):
os.makedirs(destination_directory)
move(os.path.join(directory_path, filename), os.path.join(destination_directory, filename))
