使用os.rename()重命名火影视频时触发WinError 123错误的解决办法

Got it, let's break down why you're hitting this WinError 123 and fix it step by step.

The Core Issue #

First off, that error is happening because Windows doesn't allow colons (:) in file names. Your new file name format includes Episode: 003, which violates Windows' filename syntax rules—that's exactly why you're getting the "filename syntax incorrect" error.

Step-by-Step Fixes #

1. Replace the Colon in Your New Filename

Change the colon to something Windows accepts—like a dash, or just remove it entirely. For example, update your new_name line to:

new_name = f"{mo.group(1).title()} {mo.group(3).title()}, Episode - {mo.group(7)}{ext[1]}"

Or if you prefer a cleaner look without extra punctuation:

new_name = f"{mo.group(1).title()} {mo.group(3).title()} Episode {mo.group(7)}{ext[1]}"

2. Add Safeguards to Avoid Other Potential Issues

While we're at it, let's make the script more robust to prevent other headaches:

• Skip folders: Don't try to rename directories in your target folder.
• Filter non-video files: Only process actual video files (like .mkv, .mp4, .avi) to avoid accidental changes to other files.
• Use absolute paths: Avoid relying on os.chdir()—it can lead to unexpected behavior if your script runs in the wrong context.

Updated Full Script #

Here's the revised script with all these fixes:

import os
import re

def rename_files():
    folder_path = r"C:\Users\Caleb\Videos\Anime\Naruto Shippuden"
    # Define valid video extensions to process
    valid_extensions = ('.mkv', '.mp4', '.avi', '.mov')
    
    for file in os.listdir(folder_path):
        file_path = os.path.join(folder_path, file)
        
        # Skip directories
        if not os.path.isfile(file_path):
            print(f"Skipping directory: {file}")
            continue
        
        # Skip non-video files
        ext = os.path.splitext(file)
        if ext[1].lower() not in valid_extensions:
            print(f"Skipping non-video file: {file}")
            continue
        
        # Your regex pattern (left as-is, but you can verify groups if needed)
        nameRegex = re.compile(r'.?(Naruto(-?)).'
                              r'(Shi(p)+(u)+den)'
                              r'(_-_|\\s-\\s|\\sEpisode\\s|-_Season_17_Episode_| Episode |_)'
                              r'((\\d\\d\\d)(-\\d\\d\\d)?)', re.I)
        mo = nameRegex.search(file)
        
        if mo is None:
            print(f'No match found for: {file}')
            continue
        
        # Generate new name without illegal characters
        new_name = f"{mo.group(1).title()} {mo.group(3).title()}, Episode - {mo.group(7)}{ext[1]}"
        new_file_path = os.path.join(folder_path, new_name)
        
        # Optional: Print before renaming to verify changes
        print(f"Renaming: {file} -> {new_name}")
        
        # Perform the rename
        os.rename(file_path, new_file_path)

rename_files()

Quick Debug Tip #

If you're unsure about your regex groups, add print(mo.groups()) right after the mo = nameRegex.search(file) line. This will show you all captured groups, so you can confirm that mo.group(7) is indeed the episode number you want.
