Python raise exception within nested try
我在try中有一个嵌套的try / except块，我想提出错误，然后从方法中断，但它继续。
1 2 3 4 5 6 7 8 9 10 11 | try: #stuff try: #do some stuff except: raise CustomException('debug info') #do some more stuff except CustomException: #stuff #do even more stuff return stuff |
目前，在引发CustomException(第5行)之后，它会跳转到except(第7行)然后继续并最终返回。 我希望它在升起时能够突破，但不会被其他人抓住。 它仍然需要捕获CustomException，如果它发生在'#do some more stuff'并继续。
怎么样改变try-except的结构如下？
1 2 3 4 5 6 7 8 9 10 | try: #do some stuff except: raise CustomException('debug info') try: #do some more stuff except CustomException: #stuff #do even more stuff return stuff |
只需编写
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | try: #stuff try: #do some stuff except: raise CustomException('debug info') #do some more stuff except CustomException: #stuff raise ## KM: This re-raise the exception ## KM: This wont be executed if CustomException('debug info') was raised #do even more stuff return stuff |
