Question

I have this line in a useful Bash script that I haven’t managed to translate into Python, where ‘a’ is a user-input number of days’ worth of files to archive:

find ~/podcasts/current -mindepth 2 -mtime '+`a`+' -exec mv {} ~/podcasts/old \; 

I am familiar with the os.name and getpass.getuser for the most general cross-platform elements. I also have this function to generate a list of the full names of all the files in the equivalent of ~/podcasts/current:

def AllFiles(filepath, depth=1, flist=[]):     fpath=os.walk(filepath)     fpath=[item for item in fpath]     while depth < len(fpath):         for item in fpath[depth][-1]:             flist.append(fpath[depth][0]+os.sep+item)         depth+=1     return flist 

First off, there must be a better way to do that, any suggestion welcome. Either way, for example, ‘AllFiles(‘/users/me/music/itunes/itunes music/podcasts’)’ gives the relevant list, on Windows. Presumably I should be able to go over this list and call os.stat(list_member).st_mtime and move all the stuff older than a certain number in days to the archive; I am a little stuck on that bit.

Of course, anything with the concision of the bash command would also be illuminating.

import os import shutil from os import path from os.path import join, getmtime from time import time  archive = 'bak' current = 'cur'  def archive_old_versions(days = 3):     for root, dirs, files in os.walk(current):         for name in files:             fullname = join(root, name)             if (getmtime(fullname) < time() - days * 60 * 60 * 24):                 shutil.move(fullname, join(archive, name))
