Question

我尝试连接一个小脚本，以便查找目录文件是否在24小时内创建

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

所以我尝试了＆＃34; datetime＆＃34;和.timedelta来执行数学运算，但我无法从目录中获得创建时间。

import datetime

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

感谢您的时间：D

Answer 1

os.path.getctime(path)返回“自纪元以来的秒数”（Unix时间）。要将其与当前时间进行比较，请使用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()返回the creation time for path on Windows but on other systems (Unix) it may return the time of the last metadata change。

Answer 2

这是一个解决方案

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

Python：将创建目录时间与datetime.timedelta进行比较
