比较日期以检查旧文件 [英] Comparing dates to check for old files

问题描述

我想检查文件是否早于一定时间（例如2天）。

I want to check if a file is older than a certain amount of time (e.g. 2 days).

我设法以这样的方式获得文件创建时间方式：

I managed to get the file creation time in such a way:

>>> import os.path, time
>>> fileCreation = os.path.getctime(filePath)
>>> time.ctime(os.path.getctime(filePath))
'Mon Aug 22 14:20:38 2011'

现在如何检查是否已超过2天？

How can I now check if this is older than 2 days?

我在Linux下工作，但跨平台解决方案会更好。干杯！

I work under Linux, but a cross platform solution would be better. Cheers!

推荐答案

now = time.time()
twodays_ago = now - 60*60*24*2 # Number of seconds in two days
if fileCreation < twodays_ago:
    print "File is more than two days old"
