这篇文章主要介绍了Python实现监控程序执行时间并将其写入日志的方法,实例分析了Python日志操作的相关技巧,需要的朋友可以参考下

本文实例讲述了Python实现监控程序执行时间并将其写入日志的方法。分享给大家供大家参考。具体实现方法如下：

									# /usr/bin/python

									# -*- coding:utf-8 -*-

									from time import time

									def logged(when):

									  def log(f,*args,**kargs):

									    print '''

									         called:

									          functions:%s

									          args: %r

									          kargs: %r

									    '''  % (f,args,kargs)

									  def pre_logged(f):

									    def wrapper(*args,**kargs):

									      log(f,*args,**kargs)

									      return f(*args,**kargs)

									    return wrapper

									  def post_logged(f):

									    def wrapper(*args,**kargs):

									      now = time()

									      try:

									        return f(*args,**kargs)

									      finally:

									        log(f,*args,**kargs)

									        print "time delta:%s" % (time()-now)

									    return wrapper

									  try:

									    return {"pre":pre_logged,"post":post_logged}[when]

									  except KeyError,e:

									    raise ValueError(e),'must be "pre" or "post"'

									@logged("post")

									def hello(name):

									  print "hello,",name

									hello("world!")

									'''

									等同于： hello = logged("post")(hello("world!"))

									'''
