defslow_function():time.sleep(2)slow_function() 通过将@timing_decorator放在函数定义之前,可以在函数执行前后记录执行时间。 带参数的装饰器 装饰器可以带参数,这使得它们更加通用。 以下是一个带参数的装饰器示例,用于指定最大重试次数: 代码语言:javascript ...

看descriptor的时候看到了,普通函数其实也是一个类的实例,function类,只是因为定义有特殊的__get__方法,所以才有各种function, bound method之类的表现。 那么既然def xxx的时候会产生一个function类的实例,那么在这个实例里def __get__()的时候不是又会产生一个function的实例?这不是发生递归定义了吗?

However, we can achieve this, by inspecting the environment such as using the globals(), locals(), or the inspect module. Let's dive into the article to learn more about getting a variable name as a string. Using Python globals() Function The Python globals() function is used to return...
