关于语法糖参数的实现

import time

        res = func()
        stop_time=time.time()
        print(‘程序运行时间%s‘%(stop_time-start_time))
　　　　 return res
    return wrapper

@timmer#test=timmer(test)
def test():
    time.sleep(3)
    print(‘test函数运行完毕‘)

test()

import time

            stop_time = x()
            print(‘%s程序运行时间%s‘ % (y,(stop_time - start_time)))
            return res

        return inner

    return outer

    print(‘test函数运行完毕‘)
