Python：将创建目录时间与datetime.timedelta进行比较

Question

I try to wire a little script in order to find if a directory file was created in the las 24 hours

import time

path = /some/path/dir
currentTime = time.strftime("%c")
print currentTime   # Tue Sep 15 18:08:54 2015
if os.path.isdir(path):
    created = time.ctime(os.path.getctime(path)) 
    print created   # Thu Sep 25 17:29:28 2014
    if created > 24 hours: # time don't have comparison  
        # do someting

So i trying with "datetime" and .timedelta to perform the maths, but i not able to get the creation time from the directory.

import datetime

print datetime.datetime(os.path.getctime(path))
    # AttributeError: 'module' object has no attribute 'datetimep'

Thanks for your time :D

Answer 1

os.path.getctime(path) returns "seconds since epoch" (Unix time). To compare it with the current time, use time.time() :

import os
import time

DAY = 86400 # seconds -- POSIX day
if (time.time() - os.path.getctime(path)) > DAY:
    print("more than 24 hours have passed")

getctime() returns the creation time for path on Windows but on other systems (Unix) it may return the time of the last metadata change .

Answer 2

Here's one solution

if time.mktime(time.localtime()) - os.path.getctime(path) < 24 * 60 * 60:
