Need help with filename cleanup challenge

Can someone please comment on this code for the filename cleanup challenge? I can get it to work in my Python REPL, but not on Treehouse. Thanks!

consistency.py 
import os
import re

# Filenames consist of a username (alphanumeric, 3-12 characters)
# and a date (four digit year, two digit month, two digit day),
# and an extension. They should end up in the format
# year-month-day-username.extension.

# Example: kennethlove2-2012-04-29.txt becomes 2012-04-29-kennethlove2.txt

def cleanup(path):
    year = re.search(r'[0-9]{4}', path).group(0)
    #moda = re.search(r'-[0-9]{2}-[0-9]{2}', path).group(0)
    #name = re.search(r'[\w]{3,12}-', path).group(0)
    #name = name.rstrip("-")
    #extn = re.search(r'\.[\w]{0,3}', path).group(0)
    return year + moda + '-' + name + extn
