functools.wraps装饰器的作用
： https://www.dazhuanlan.com/2019/12/26/5e0409c45a205/ 对比测试 先看一个未使用functools.wraps的装饰器: def time_consuming_deco __name__, end - start)) return wrapper 下面使用上面的装饰器: @time_consuming_deco def f(): for i in range __name__) 运行结果为: f time consuming: 22.99853515625 ms f. __name__ : wrapper 再看一个使用了functools.wraps的装饰器: def time_consuming_deco(func): """ 还是上面计算运行func __name__, end - start)) return wrapper 再次运行上面的测试程序结果如下: f time consuming: 22.99853515625 ms f.
