Which version of Python?

I ran it through 3.10 and got nothing like that.

Try this:

import os
import re
with os.scandir() as i:
   for entry in i:
     if entry.is_file():
       ## Use named groups for easy use of captured data:
       ## Also, put it all in one regex for easy positional grabbing of
       ## elements:
       ## Finally, wrapped for legibility in email, etc.:
       info = re.search(
         "^"
         + "(?P<title>.*)"
         + "\.(?P<year>\d{4})\."
         + "(?P<res>\d+p)"
         + ".*\.(?P<ext>.*)"
         + "$",
         entry.name)
       print( f"title: {info.group('title')}")
       print( f"year: {info.group('year')}")
       print( f"resolution: {info.group('res')}")
       print( f"extension: {info.group('ext')}")


Output:

title: Zero.Dark.Thirty
year: 2012
resolution: 720p
extension: mp4
