func =lambda: (_for_in()).throw(Exception('this is an exception')) 方法二 如果不在乎异常信息是什么: func =lambda:1/0 不难理解,这个函数会抛出ZeroDivisionError。这种方法其实代表了一类,比如也可以写成: func =lambda: [][0] 这类实现就是在lambda后面写一定会抛出

Python用异常对象(exception object)表示异常情况,遇到错误后,会引发异常。如果异常对象并未被处理或捕捉,程序就会用所谓的回溯(Traceback,一种错误信息)终止执行。 raise 语句 Python中的raise 关键字用于引发一个异常,基本上和C#和Java中的throw关键字相同,如下所示: ...
