#!/usr/bin/env python # -*- coding:utf-8 -*- import time def wrapper(func): def deco(*args,**kwargs):#deco接收参数"sunwei"和24 start = time.time() func(*args,**kwargs)#执行此句时,相当于test1("sunwei",24) stop = time.time() print("the func run %s"%(stop - start)) return deco #这里的【@wrapper】等于【test1 = wrapper(test1)】,wrapper(test1),将test1函数以实参的形式传递给wrapper函数,wrapper函数将会把deco函数的内存地址作为返回值返回给变量test1,而此时test1变量所指引的值相当于是deco函数的内存地址,如果test1()则将会执行deco函数 @wrapper def test1(name,age): time.sleep(3) print("in the test1...") print("---->%s:%s"%(name,age)) #下面语句相当于deco("sunwei",24) test1("sunwei",24)
