1. decorator中只做定义和初始化的工作,不要用decorator来执行某个操作。或者说,decorator不要有除了定义以外的副作用 例如,严格杜绝下面的用法: def execute_once(f): f('test') @execute_once def my_func(param): ... 没有人会从代码中判断这个函数会在import的时候自动执行。而且,没有人会懂为什么my...
my_decorator , 下面的两段代码是等效的: class C(object): @my_decorator def method(self): # method body ...class C(object): def method(self): # method body ... method = my_decorator(method) 优点:优雅的在函数上指定一些转换. 该转换可能减少一些重复代码, 保持已有函数不变(enforce invariant...
