What is the best way to get a list of all files in a directory, sorted by date [created | modified], using python, on a windows machine?

Update: to sort dirpath's entries by modification date in Python 3:

import os
from pathlib import Path

paths = sorted(Path(dirpath).iterdir(), key=os.path.getmtime)

_{(put @Pygirl's answer here for greater visibility)}

If you already have a list of filenames files, then to sort it inplace by creation time on Windows (make sure that list contains absolute path):

files.sort(key=os.path.getctime)

The list of files you could get, for example, using glob as shown in @Jay's answer.

^{old answer} Here's a more verbose version of @Greg Hewgill's answer. It is the most conforming to the question requirements. It makes a distinction between creation and modification dates (at least on Windows).

#!/usr/bin/env python
from stat import S_ISREG, ST_CTIME, ST_MODE
import os, sys, time

# path to the directory (relative or absolute)
dirpath = sys.argv[1] if len(sys.argv) == 2 else r'.'

# get all entries in the directory w/ stats
entries = (os.path.join(dirpath, fn) for fn in os.listdir(dirpath))
entries = ((os.stat(path), path) for path in entries)

# leave only regular files, insert creation date
entries = ((stat[ST_CTIME], path)
           for stat, path in entries if S_ISREG(stat[ST_MODE]))
#NOTE: on Windows `ST_CTIME` is a creation date 
#  but on Unix it could be something else
#NOTE: use `ST_MTIME` to sort by a modification date
        
for cdate, path in sorted(entries):
    print time.ctime(cdate), os.path.basename(path)

Example:

$ python stat_creation_date.py
