Python Script - Rename TV Show Titles

Automatically Renaming Video Files For Plex

Rename Title Script

The idea with this is to take an existing folder with subfolders of TV show episodes, and reformat them as such:

S04E13 - The Nightman Cometh.mp4 -> The Nightman Cometh - S04E13.mp4

This is so Plex knows how to organize the episodes into a parent show.

import os
import re
 
def rename_files_in_directory(root_dir):
    pattern = re.compile(r'^(S\d{2}E\d{2}) - (.+?)(\..+)$')
    
    for foldername, subfolders, filenames in os.walk(root_dir):
        for filename in filenames:
            match = pattern.match(filename)
            if match:
                season_episode, title, extension = match.groups()
                new_filename = f"{title} - {season_episode}{extension}"
                old_path = os.path.join(foldername, filename)
                new_path = os.path.join(foldername, new_filename)
                
                try:
                    os.rename(old_path, new_path)
                    print(f'Renamed: "{filename}" -> "{new_filename}"')
                except Exception as e:
                    print(f'Error renaming "{filename}": {e}')
 
if __name__ == "__main__":
    folder_path = input("Enter the folder path: ")
    rename_files_in_directory(folder_path)
