Python, Deleting all files in a folder older than X days

Question

I'm trying to write a python script to delete all files in a folder older than X days. This is what I have so far:

import os, time, sys      path = r"c:\users\%myusername%\downloads" now = time.time()  for f in os.listdir(path):   if os.stat(f).st_mtime < now - 7 * 86400:     if os.path.isfile(f):       os.remove(os.path.join(path, f)) 

When I run the script, I get:

Error2 - system cannot find the file specified,

and it gives the filename. What am I doing wrong?

Answer 1

os.listdir() returns a list of bare filenames. These do not have a full path, so you need to combine it with the path of the containing directory. You are doing this when you go to delete the file, but not when you stat the file (or when you do isfile() either).

Easiest solution is just to do it once at the top of your loop:

f = os.path.join(path, f) 

Now f is the full path to the file and you just use f everywhere (change your remove() call to just use f too).
