给test函数加个装饰器！

import time
def timer(func):
    def deco(*args,**kwargs):
        start_time=time.time()
        func(*args,**kwargs)
        stop_time=time.time()
        print("the func run time is %s" %(stop_time-start_time))
    return deco

@timer  #test1=time(test1)
def test1():
    time.sleep(3)
    print('in the test1')

@timer
def test2(name,age):
    time.sleep(3)
    print (name,age)

test1()
test2('Sins Ze',47)
