如何用Python移除影视子文件夹名称中的指定冗余内容（如720p、BluRay）

Hey there! Let's fix those cluttered movie/TV subfolder names once and for all. I've put together a complete, safe Python solution that handles all those annoying tags like 720p, BluRay, x264, and more. Here's how it works:

Core Approach #

We'll build a script that:

• Targets all common redundant media tags (you can easily expand this list)
• Scans your target directory (and nested subfolders if needed)
• Cleans up folder names by removing tags, fixing messy separators, and avoiding naming conflicts
• Includes safety checks to prevent accidental overwrites

Full Code Implementation #

import os
import re

def clean_media_folders(root_directory):
    # Define all redundant tags to remove (add/remove based on your needs)
    redundant_tags = [
        r'720p', r'1080p', r'2160p', r'4K', r'8K',
        r'BluRay', r'WEB-DL', r'WEBRip', r'DVDrip', r'BDRip',
        r'HDR', r'HDR10', r'DV', r'DolbyVision',
        r'x264', r'x265', r'HEVC', r'AVC',
        r'AC3', r'DD5.1', r'DD7.1', r'Atmos', r'DTS',
        r'REMUX', r'Extended', r'Unrated', r'Director\'s Cut',
        r'YIFY', r'ETRG', r'RARBG'  # Add common release groups here
    ]

    # Compile regex pattern: match tags regardless of case, with word boundaries
    tag_pattern = re.compile(
        r'\b(' + '|'.join(redundant_tags) + r')\b',
        re.IGNORECASE
    )

    # Walk through all subfolders in the target directory
    for current_dir, subdirs, files in os.walk(root_directory):
        for folder_name in subdirs:
            original_name = folder_name
            
            # Step 1: Strip out all redundant tags
            cleaned_name = tag_pattern.sub('', original_name)
            
            # Step 2: Clean up messy separators (dots, hyphens, underscores → spaces)
            cleaned_name = re.sub(r'[\.\-_]+', ' ', cleaned_name)
            
            # Step 3: Remove extra spaces (leading, trailing, and consecutive)
            cleaned_name = re.sub(r'\s+', ' ', cleaned_name).strip()

            # Skip if the name is already clean
            if cleaned_name == original_name:
                continue

            # Build full paths for renaming
            original_path = os.path.join(current_dir, original_name)
            new_path = os.path.join(current_dir, cleaned_name)

            # Handle naming conflicts (add a counter if the new name already exists)
            counter = 1
            while os.path.exists(new_path):
                new_path = os.path.join(current_dir, f"{cleaned_name} ({counter})")
                counter += 1

            # Execute the rename (with error handling)
            try:
                os.rename(original_path, new_path)
                print(f"✅ Renamed: '{original_name}' → '{os.path.basename(new_path)}'")
            except Exception as e:
                print(f"❌ Failed to rename '{original_name}': {str(e)}")

if __name__ == "__main__":
    # Replace this with your actual media folder path
    target_dir = "/path/to/your/media/library"  # Windows users: use r"C:\Your\Media\Path"
    
    if os.path.isdir(target_dir):
        clean_media_folders(target_dir)
        print("\n✅ All clean!")
    else:
        print("❌ Error: Target directory doesn't exist!")

Key Details & Customization Tips #

1. Expand the Tag List: Add any other redundant terms you encounter (like specific release groups, language tags you don't need, etc.) to the redundant_tags list.
2. Case Insensitive: The regex matches tags regardless of capitalization (so bluray, BLURAY, and BluRay all get removed).
3. Safety First: The script automatically adds a counter (e.g., Movie Name (1)) if the cleaned name already exists, so you never accidentally overwrite a folder.
4. Nested Folders: By default, os.walk scans all nested subfolders. If you only want to clean top-level folders, replace the os.walk loop with a simple os.listdir check for directories.

Important Pre-Run Notes #

• Backup First: Always make a copy of your media folders before running batch rename scripts—just in case!
• Test Small: Run the script on a small test folder first to verify it behaves exactly how you want.
• Permissions: Ensure you have read/write access to the target directory.
