Hello,
Also working w/o external module just the standard one:
*>>> import datetime
>>> remove_after = datetime.datetime.now() - datetime.timedelta(days=31)
>>> remove_after
datetime.datetime(2010, 12, 24, 23, 21, 10, 11315)
*
Regards
Karim

Hi, hoping for some help here. I've been trying to write a python
script (complete newb) and have spent several days trying to get
this right with no success.
I am trying to list timestamps in a directory and if they are
older than x amount of days delete the directories. It seems that
in my for loop it is only evaluating the last timestamp of the
last directory and using that timestamp to make the deletion
decision. I realize that this script isn't going to delete the
directories with evaluate as true but I haven't been able to get
that far yet...
###########start script##############
###Modules###
import os
import time
###Global Variables###
curr_t = time.time()
days = 2629743 #2629743 is 30 days in epoch time.
directory=os.path.join("/home", "userid", "python")
for r,d,f in os.walk(directory):
for dir in d:
timestamp = os.path.getmtime(os.path.join(r,dir)) ## It
seems that the below "if" statement is only comparing the
timestamp of the last directory that this variable lists.
print timestamp
if curr_t - days < timestamp: #### I am
expecting this statement to compare each timestamp of the
"directory" variable and print out if it should be deleted or not.
print "Your file will be deleted"
else:
print "File will NOT be deleted..."

Thank you for your time!

First off, I would recommend using dates and not times, this can help
make things clearer
when dealing with dates, also the dateutil module can make date math a
lot simpler (easy_install dateutil)
from datetime import datetime
from dateutil.relativedelta import relativedelta
remove_after = datetime.now() - relativedelta(days=31) # exactly 1
month prior to today
check_dir = "/path/to/whatever"
for r,d,f in os.walk(check_dir):
for dir in d:
loc = os.path.join(r,dir)
last_modified = datetime.fromtimestamp(os.path.getmtime(loc))
if last_modifed < remove_after:
print "delete old directory", loc
else:
print "keep recently modified", loc
Hope this helps,
