#2 Created at ... [Delete] [Delete and Lock User]

请问，我写的跟你也一样为什么报错了呢

def metric(fn):

    @functools.wraps(fn)

    def wrapper(*args):

        t1=time.time()

        ex=fn(*args)

        t2=time.time()

        print('%s exhauted in %s ms' %(fn.__name__,t2-t1))

    return wrapper

没返回ex，所以报错。

在return wrapper上面缩进，加上return ex
