python版本为：2.7

import os

# To delete the path and the following subfiles
PATH = r'C:\inetpub\logs\LogFiles'

            # Sets how many days old files are deleted
            endfiletime = time.time() - 3600 * 24 * DAYS_N
            if endfiletime > lastmodifytime:
				# To remove the following comment is to delete the.log suffix file
				# Comment is delete path under all files do not match
                if filename[-4:] == ".log":

time.sleep(1)
