Python實現監控程序執行時間並將其寫入日志的方法

 　　本文實例講述了Python實現監控程序執行時間並將其寫入日志的方法。分享給大家供大家參考。具體實現方法如下：

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 # /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!") ''' 等同於： hello = logged("post")(hello("world!")) '''

　　希望本文所述對大家的Python程序設計有所幫助。
