装饰器参数

#有多个函数，需要计算他们的执行时间
import time

def show_time(f):
    def inner(*x,**y):
        starttime = time.time()
        f(*x,**y)
        endtime = time.time()
        print("执行时间：%s"%(endtime - starttime))
    return inner

@show_time  #foo = show_time(foo)   @show_time同等与foo = show_time(foo)

def foo(*a,**b):
    fnum = 0
    for i in a:
        fnum += i
    print(fnum)
    print("this is foo")
    time.sleep(2)
#foo = show_time(foo)
foo(1,2,3,4,5,6)
