Common python date, log, get content Loop code snippet

The shell script and Python have been combed in the near time, and some of the common content in the script has been sorted out to form useful code fragments, which can be used directly when needed, and can be used for forgetting and thinking.
This collation of the code snippet is: Python in the date, time commonly used to get the method, record processing log logging module use, from the directory, file, named results, get the loop condition to loop.
I've organized these useful snippets in a Python script, and the tests are available.
The script reads as follows:

#!/usr/bin/env python#_*_coding:utf8_*_# Common date and time import datetime,timetoday =  Datetime.date.today () Yesterday = datetime.date.today ()  - datetime.timedelta (Days=1) Tomorrow = datetime.date.today ()  + datetime.timedelta (Days=1) Today_nyr = int ( Datetime.datetime.strftime (today,  '%y%m%d ')) Yesterday_nyr = int (Datetime.datetime.strftime ( yesterday,  '%y%m%d ')) Tomorrow_nyr = int (Datetime.datetime.strftime (tomorrow , '%y%m%d ')) Time.strftime ('%y-%m-%d %h:%m:%s ',  time.localtime (Time.time ()))  print  "now time  Is {time} ".

The above script can be executed directly using Python 3.py.
