a script to add leading zeroes in a directory recursively according to the folder structures inside

zeroes.py

import os

    for root, _, files in os.walk(folder_path):
        total_files = len(files)

        # Determine the number of digits needed
        digits = len(str(total_files))

        # Sort files for consistent renaming order
        files.sort()

        for filename in files:
            # Get the file name and extension
            name, file_extension = os.path.splitext(filename)

            # Create the new name with leading zeroes
            new_name = f"{name.zfill(digits)}{file_extension}"

            # Get the full paths
            old_path = os.path.join(root, filename)
