def out(func):

    def inner(*args):

        start = datetime.datetime.now()

        func(*args)

        end = datetime.datetime.now()

        print(end-start)

        print("out and inner")

    return inner

@out

def myfunc(*args):

    time.sleep(1)

    print("args is{}".format(args))

myfunc("lalalal")
