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?
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 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)

I've done this in the past for a Python script to determine the last updated files in a directory:
import glob import os search_dir = "/mydir/" # remove anything from the list that is not a file (directories, symlinks) # thanks to J.F. Sebastion for pointing out that the requirement was a list # of files (presumably not including directories) files = filter(os.path.isfile, glob.glob(search_dir + "*")) files.sort(key=lambda x: os.path.getmtime(x))
That should do what you're looking for based on file mtime.
EDIT: Note that you can also use os.listdir() in place of glob.glob() if desired - the reason I used glob in my original code was that I was wanting to use glob to only search for files with a particular set of file extensions, which glob() was better suited to. To use listdir here's what it would look like:
import os search_dir = "/mydir/" os.chdir(search_dir) files = filter(os.path.isfile, os.listdir(search_dir)) files = [os.path.join(search_dir, f) for f in files] # add path to each file files.sort(key=lambda x: os.path.getmtime(x))
